POEM: Mind Gravity: or, The Heft of Mental Putrefaction

depression-in-bed

Gravity pulls her head down into the pillow.

Like tar through a garden hose, thoughts flow.

Thoughts weighty, not freed of mass and matter.

As stuck in time and lost to reason as the Hatter.

Thoughts arise because they’re lighter than air.

Hers fell sodden, a lead balloon in the state fair.

The infection arose from a single putrid notion.

One drop floating free to fester across an ocean.

That she wasn’t enough. Enough for whom? Enough for what?

Unanswerable questions that congealed into a sluggish pus.

They say truth has weight, but truth lifts one to fly free.

What pulled her head to pillow was the mass of negativity.

As her thoughts hardened into a slag, devoid of truth or reason.

She summoned the strength for a search in her final season.

She scoured the four corners of the Earth for a fabled cure.

But it lie in a place close at hand, but vastly more obscure.

5 Books to Introduce You to Your Subconscious

In a world free of frontiers, the subconscious mind is the final frontier.

 

Below are a few books that I found useful. The hyperlinks forward to my review on GoodReads or the book’s GoodReads page.

 

Also, I’ve included three honorable mention books that I haven’t yet reviewed, but which seem both relevant and intriguing.

 

5.) Brainwashing by Kathleen Taylor: What makes some minds more malleable than others and how are minds bent to a given purpose? In learning the answers, one discovers that the bases of our beliefs are often more deep-seated than one might believe.

4.) Sleights of Mind by Macknik & Martinez-Conde: Magicians and mentalists are notoriously skilled at exploiting the chinks in the armor of  our minds.

3.) Subliminal by Leonard Mlodinow: Physicist and pop science writer, Leonard Mlodinow, explores the many ways in which our behavior is more influenced from the back of the house than we feel to be the case.

2.) The Tibetan Yogas of Dream and Sleep by Tenzin Wangyal Rinpoche: This is my nod to the fact that the Western scientific community isn’t the only entity that has something useful to say on this subject. Tibetan Buddhists have a long tradition (arguably predating Buddhism and into the Bon-era) of dream yoga (lucid dreaming) and our dreams offer the greatest portal to the subconscious.

1.) Incognito by David Eagleman: Eagleman tells us that our conscious mind represents the tip of the mental iceberg, and he explores the many ways in which we are subject to the vagaries of what exists below the surface.

Here are a few others.

 

The Man Who Wasn’t There by Anil Ananthaswamy: I just finished this book. In it, the author investigates whether there really is  such a thing as the self by studying a number of diseases and phenomena of the mind that look like negations of self. (e.g. Cotard’s Syndrome in which people insist they are dead, depersonalization disorder in which life seems a dream in a literal rather than poetic sense, out-of-body-experiences in which there is a hallucination that one is outside one’s body, etc.)

 

The Attention Merchants  by Tim Wu: I haven’t read this one yet, but it’s said to be good and is about how our programming is exploited to keep us clicking. If you’ve ever wondered why you can’t seem to just drop social media even when it seems like a phenomenal waste of time–why it exerts such a strong pull–this book delves into what proclivities of the mind have been seized upon.

 

Reality is Broken by Jane McGonigal: I’m about 1/3rd of the way through this one. It has some overlap with the Wu book. In it, McGonigal asks why games have so much appeal–even to the extent of becoming addictive. As with why we keep clicking, the answer has a lot more to do with the primitive parts of our mind than the high tech subject matter might suggest.

BOOK REVIEW: The Geography of Bliss by Eric Weiner

The Geography of Bliss: One Grump's Search for the Happiest Places in the WorldThe Geography of Bliss: One Grump’s Search for the Happiest Places in the World by Eric Weiner
My rating: 5 of 5 stars

Amazon page

 

This book combines travel writing with pop science discussion of what makes people happy (or unhappy.) Weiner travels to ten countries in pursuit of happiness, and reflects upon the cultural components of bliss.

Some of the countries, like Switzerland and Iceland, rank among the world’s happiest in international surveys. Some of the countries, such as Qatar and America, have every reason to be happy, but aren’t necessarily as blissful as the rest of the world would expect. Some of them, like India and Thailand, have good reason to be unhappy, and yet they manage to be global exemplars of happiness [at least within certain domains.]

Then there are a few nations that have unique relationships to happiness. Bhutan has a national policy on happiness [plus it’s a Buddhist country, and Buddhism probably offers the most skillful explanation of what it takes to be happy of any world religion.] Moldova provides a counterweight as it’s one of the least happy countries in the world. Weiner visits the Netherlands in part because one of the biggest academic centers studying happiness is located in Rotterdam, but it also offers an opportunity to study whether the country’s unbridled hedonism (drugs and prostitution are legal) correlates to happiness. That leaves Great Britain, a country known for wearing the same happy face as its sad, terrified, and enraged faces.

I’ve been to half of the countries on Weiner’s itinerary, and—of the others—I’ve been to countries that share some—though not all—of the cultural constituents of happiness. (e.g. I haven’t been to Qatar, but I’ve been to the UAE. I haven’t been to Moldova, but I’ve seen somewhat less grim Eastern European states. I haven’t been to Switzerland or Iceland but I’ve been to cold countries in Western Europe. I haven’t been to Bhutan, but I’ve been in areas where Tibetan Buddhism was the dominant cultural feature.) This allowed me to compare my experiences with the author’s, as well as to learn about some of the cultural proclivities that I didn’t understand during my travels. And I did find a lot of common ground with the author, as well as learned a lot.

I found this book to be interesting, readable, and funny. Weiner has a wacky sense of humor that contributes to the light-hearted tone of the book—perfect for the subject. That said, some people may be offended because the author doesn’t pull punches in the effort to build a punchline, and this sometimes comes off as mocking cultures. However, in all cases—even that of Moldova—Weiner does try to show the silver lining within each culture.

The paperback edition I read had no graphics or ancillary matter. There are no citations or referred works (except in text), and the chapters are presented as journalistic essays. The chapters largely stand alone, and so one could read just particular countries of interest. He does refer back to events that happened in earlier chapter or research that related to another country’s cultural proclivities, but not often. The first chapter, on the Netherlands, would be a good one to read first because he describes many of the scientific findings on happiness in that one.

I would recommend this book for anyone interested in what makes some places happier (or sadder) than others.

5 Hyphenated Yogas That Miss the Point of Yoga

The laissez-faire and easy-going yoga community has spawned some phenomenally ridiculous mergers. I have “yoga” as a term on Google News, and almost every week I get fed a new example. I’m not saying every new approach to yoga is bad, but there’s one disturbing trend–i.e. the distraction yoga.

 

In the title, I refer to “hyphenated yogas,” but what I’m really ranting about is “distraction yogas.” A distraction yoga is one in which an element is brought into the practice so that one doesn’t have to keep one’s mind on one’s breath, alignment, and / or mental state. (Because who wants to think about that shit when one can be thinking “Wow, that kitten sure is cute.” or–believe it or not–“This beer has hoppy undertones.”)

 

Now before I get accused of hating puppies or beer, let me point out that nothing could be further from the truth. What I’m ranting against is the notion that you can marry any two good things and make a great thing. If you don’t believe me, please allow me to dip my nachos in your banana split. See, there are plenty of things that are awesome independently that make abominations when forced together.

 

I’ll include links as I go, lest you think I made this stuff up for hilarity’s sake.

 

5.) Beer Yoga: This is one of the most recent and intriguing distraction yogas. I’m not saying that one needs to follow a strict Vedic approach to life to practice yoga, but–come on–could you stop drinking for a couple hours to pretend your body is a temple (or at least that it’s not sitting in a trailer park with the windows busted out.) Unless “calf slaughter-yoga” catches on, it’s hard to imagine a less yoga-like practice than consuming intoxicants during the practice of yoga. By the way, there’s also a marijuana yoga, but I’ll lump these together as intoxicant yogas.

4.) Goat Yoga: This is one of many “animal yogas.” Like the others, the point is to have cute creatures around. How it’s supposed to help one’s yoga, I can’t fathom. Actually, I can fathom the suggested logic, probably something to do with calming and engendering feelings of compassion and well-being. But, ultimately it’s distraction by cuteness. Note: you can also do yoga with cats, dogs, horses, and probably river otters.

3.) Karaoke Yoga: Talk about distraction–nothing better than pounding music and reading a prompter to keep one’s mind off that ache in one’s hamstring.

karaoke_yoga

 

2.) Rave Yoga / Club Yoga: This might be a cheat because it’s similar to the previous one on the list, and I’m trying to lump these together so as to not be too repetitive. However, it’s not exactly the same, and is the perfect example of a distraction yoga. (There’s also Harmonica yoga and other musical yogas, but I won’t double-dip anymore.)

bombay_yoga-2e16d0ba-fill-735x490

 

1.) Tantrum Yoga: It wasn’t easy to determine whether I’d include this one or not. On the one hand, it’s not a distraction yoga in the sense that the others are. On the other hand, it takes the award for being least yoga like on the grounds that it’s not about dispassionately witnessing one’s emotional state but rather feeding one’s negative emotions. Note that I don’t group laughter yoga into the same class. I’m not sure whether laughter yoga is beneficial (or to what degree it’s a yoga), but I know that many people benefit from it because it bolsters positive emotional states.

tantrum

 

Now, one may have noticed that there are many seemingly strange (hyphenated) yogas that I haven’t mentioned. I haven’t said a thing about surf board-yoga, stripper pole-yoga, or acro-yoga–and I specifically excluded Laughter Yoga from the wrath of my rant. That’s because this isn’t a rant about people being innovative or non-traditional, it’s about people missing the point of what yoga is supposed to be (i.e. a means to quiet the mind.) I don’t know whether I can see myself doing yoga on a surf board or a stripper pole, but I’m certain that one has to give it one’s full attention–it’s not about finding a distraction to make yoga more palatable to hipsters.

BOOK REVIEW: Brain Rules by John Medina

Brain Rules: 12 Principles for Surviving and Thriving at Work, Home, and SchoolBrain Rules: 12 Principles for Surviving and Thriving at Work, Home, and School by John Medina
My rating: 4 of 5 stars

Amazon page

 

As the title suggests, this is a book of guidance about how to get the most out of one’s mental life. Medina goes a mile wide, looking at twelve areas in which one can improve the performance of one’s brain, including: exercise, attention, memory, sleep, stress management, sensory integration, and visual acuity. It also has chapters that explain how evolution and gender affect the way in which one’s brain operates.

After an Introduction that sets up the premise of the book, there are twelve chapters. The first chapter explores the well-documented connection between exercise and mental performance, and offers insight into what type of exercise has been shown to be most helpful to the brain. The second chapter pertains to our brain’s evolutionary history. The conscious mind housed in the cortex is but the top floor of a multi-story enterprise, and understanding this has important ramifications for how one gets the most out of one’s brain. Chapter 3 explores the way brains are wired, which turns out to be flexibly and diversely. By flexibly, I mean that brains can be rewired by way of what is called neuroplasticity on the proviso that neurons that fire together wire together. By diversely, I mean that each individual’s brain is a bit different, and these differences can explain how someone gifted in one domain may be an idiot in other aspects of life. The next chapter deals with attention and explains why humans suck at multi-tasking (despite thinking they are the bomb) and why an extended ability to concentrate is essential to success.

The next two chapters both deal with memory, but with different types of memory—each having its own unique considerations. The first, chapter five, describes the peculiarities of short-term memory, that part of the memory that can hold a finite amount of data points at the forefront of our minds for a limited period. Chapter six deals with long-term memory, the part that holds vast stockpiles of information for extended periods (sometimes across a lifetime) but with lower fidelity and accuracy than we generally believe. While the rule offered for both forms of memory is simple—i.e. repetition is key—there is much to consider in the details. For starters, there are many other ways to divide up memory other than with respect to the short-term / long-term dichotomy (e.g. procedural v declarative) and differences in the way these types of memory work affect how they are both optimized.

The influence of sleep on mental performance is the subject of chapter seven. There is a vast pile of research on this subject, including a number of famous cases of extreme sleep deprivation—some of which are touched upon herein. It’s true that there is a great deal of variation in how people sleep (e.g. morning v non-morning people, and those who can power nap and those who can’t.) However, one thing remains unambiguous and that’s that we need sleep and must have full cycles of it in order to not suffer mental degradation. Chapter 8 is about how stress can kill mental performance. Of course, not all stress is the same. When one feels in control, short bursts of stress can be just the motivator one needs, but when feeling out of control stress can become crippling.

Chapters 9 and 10 are both about the senses. The first, nine, explains how one can obtain synergistic outcomes in a multi-sensory environment, and the second focuses on vision—arguably our most dominant sense. Our sensory experience is much more a product of the brain (and much less a pure representation of the outside world) than we tend to believe.

Chapter 11 reports on the gender differences that have been discovered with respect to brains. Before anyone lights a torch or sharpens a pitchfork, this isn’t the old “boys do math and girls do language” line. The differences are more nuanced, and it’s not clear in every case that the differences matter—or how. E.g. Men have bigger amygdala (involved in emotional response) and produce serotonin more quickly. While it’s not clear that these differences make a big difference, it’s know that men and women use their amygdala differently in times of stress, men activate the right amygdala and tend to remember more of the gist of events while women trip the left and remember more emotional details. The last chapter is about our human proclivity to explore, but it focuses heavily on infancy and childhood, during which the world is novel and the impulse to explore is at its height.

Each chapter ends with a summary box that both restates the rule and offers a few bullet points of key takeaway lessons, which may either be more specific guidance or summary of relevant research findings. There aren’t many functional graphics—by functional I mean as opposed to the ornamental drawings used throughout. I only remember one brain drawing. However, the reason for the dearth of graphics may be that there is a link to a 45 minute video that one can access, and the publisher probably thought that was a much more useful way to impart graphic information. It should also be noted that in the Kindle edition that I have, the references are also on-line.

I found this book to be useful. As I mentioned, it’s a broad overview. One can get books that dive more deeply into all of the topics addressed. But this is a nice mix of popular science and self-help. It’s readable, and the summaries and concise statement of rules help make the content stick more effectively.

I’d recommend this book for those who are seeking a book that covers a lot of ground, and which offers practical guidance as to how to put scientific discoveries on the brain into use in one’s own life.

BOOK REVIEW: The Discourse Summaries by S.N. Goenka

Discourse SummariesDiscourse Summaries by S.N. Goenka
My rating: 4 of 5 stars

Amazon page

 

I began reading the summaries before I attended the Vipassana meditation 10-day course. While most of one’s days are spent in meditation, each evening they play video-taped discourses by S.N. Goenka, with each running for an hour to an hour-and-a-half. As the title suggests, this book consists of edited transcripts of those talks. As the course is known for being challenging (approximately 10 hours/day in meditation, noble silence [no talking–or even acknowledging–anyone but the teacher and staff], and no distractions [no phones, no books, no journals, no i-Pods, etc.]), reading the discourses was a way to mentally prepare for the course. (Though I’d already read a book call “Equanimous Mind” by an individual who’d completed the course.)

Let me provide background for those unfamiliar with Vipassana meditation. It’s nominally a Theravadan Buddhist practice, but its religiosity is stripped to a minimum and it’s presented in a largely secular manner. That doesn’t mean that a scientifically-minded skeptic such as myself isn’t occasionally left scratching his head and thinking “that’s not right.” However, it’s repeatedly emphasized that one should take what is of value to oneself and leave the rest behind, and so while there are a few notions mentioned during the discourses that aren’t supported by evidence, one needn’t believe anything controversial to benefit from the practice. (e.g. Karma and reincarnation are mentioned, but if one doesn’t believe those are likely realities, it doesn’t change the effectiveness of the meditation.)

Moving on, Theravadan Buddhism is the branch that is most commonly practiced in Southeast Asia. (It’s sometimes called Hinayana, but—as I learned during a discourse—that’s considered a derogatory term by many Theravadans. “Hinayana” means “lesser vehicle” in contrast to Mahayana’s “greater vehicle,” and the implication is that it’s a path by which only a more select group can achieve enlightenment. One can readily see why this would be objectionable to Vipassana practitioners as they emphasize that the practice is available to everybody [one need not even identify as Buddhist] and that the practice is the heart of the path to enlightenment.) Vipassana meditation involves systematically scanning one’s body for sensations and acknowledging them without attaching positive or negative thoughts and labels to them. The idea is to train oneself to not mindlessly react to sensations, nor to mindlessly attach values to them.

There are eleven discourses, corresponding to the days over which one is at meditation center. However, the new information is mostly in the discourses from days one through nine. The last two discourses consist of a review and a discussion of to how to keep one’s practice going—should one choose to do so.

The discourses present two types of information. On one hand, they provide a primer on Buddhist philosophy regarding the path to enlightenment. For example, Goenka explains the Four Noble Truths and the Eight-fold Path. The Four Noble Truths describe human suffering, its causes, and the path to moving beyond this suffering. That path brings one to the Eight-fold Path which describes eight areas in which one must properly align one’s approach in order to eliminate said suffering.

On the other hand, the discourses provide information about the meditational practices and the logic that informs them. During the first few days of the course, one focuses on respiration and related sensations over a progressively smaller area around and on the nose. Then, on the fourth day, one gets into the Vipassana practice as mentioned above (scanning the body for sensation), but one practices several variations of this over the last few days of the course. It seems that one practices these different ways both because one becomes capable of more challenging approaches and because not everybody experiences the same types of sensations, and so some methods work better for some types of sensations than others. To give an example, on day one might scan one arm at a time, but then one shifts to scanning both arms simultaneously.

There are no graphics and the only ancillary matter consists of a list of Pali quotations as well as a Pali term glossary. (Pali is the language in which the Buddhist scriptures were originally written.) However, there was really no need for either graphics or notations.

I found these summaries were worth reading even having gone through the course and heard the discourses at the center. For one thing, there’s a good amount of information packed into the lectures. While it’s not hard to understand, there’s a high density of information content. For another, Goenka was a charming and humorous individual, so it’s not boring to watch the taped discourses even if one has previously read them.

I would definitely recommend reading the Discourse Summaries if one is considering taking the Vipassana course.

BOOK REVIEW: Hallucinations by Oliver Sacks

HallucinationsHallucinations by Oliver Sacks
My rating: 5 of 5 stars

Amazon page

 

Hallucinations are among the most captivating, yet misunderstood, phenomena of the mind. In the popular imagination, they are synonymous with losing one’s grip on reality and are considered evidence of a full-blown psychosis. However, there are a great variety of causes and forms of hallucination, many of which occur among the sane. What Sacks provides in this book is a survey of the forms of hallucination through exploration of cases and anecdotes. To emphasize the point that hallucinations aren’t just for the insane, Sacks doesn’t arrange the book around the idea sanity and insanity. Cases of mental illness are peppered throughout, but there are even more cases of people who fully realize that their hallucinated sensory experiences aren’t real. In fact, he starts with Charles Bonnet Syndrome, hallucinations among blind individuals who are often scared to discuss the phenomena for fear they will be labeled insane even though they know they aren’t really seeing anything. (The brain’s abhorrence of under-stimulation is a recurring theme in the book.)

As mentioned, the approach of the book is to discuss cases of hallucination, and not so much to delve into the research on causes and treatments. This anecdotal approach makes the book readable and offers a unique and intimate insight into hallucination, but it doesn’t drill down into the brain science as much as some might like. This will no doubt be a positive for many, and a negative for others. The author describes several of his own hallucinatory experiences related to drug use, drug withdrawal, and migraine headaches. As I understand it, that level of candor was par for the course for Sacks (though this is the first of his books that I’ve read.) At any rate, his personal experience offers a particularly vivid portrait, and moves the book beyond the sterile feel often found in scientific works.

The book consists of 15 chapters, organized by types / causes of hallucination. After an introduction and the aforementioned chapter on Charles Bonnet Syndrome, there’s a chapter on sensory deprivation hallucinations that’s aptly entitled “the prisoner’s cinema.” Chapters three and four are on olfactory and auditory hallucinations, respectively. The fifth chapter focuses on cases of hallucination experienced by those with Parkinson’s Disease. Chapter six is entitled “Altered States,” but it deals largely with drug-induced hallucinations (it should be pointed out other “altered states” of consciousness, notably sleep, are dealt with in other places), and it’s where Sacks’ personal story begins to be detailed. The next chapter deals with migraine headache related phenomena, and—as the author suffered from such headaches—his story is also imprinted on this chapter.

Chapter eight deals with epilepsy, and, like the Sam Kean book that I reviewed yesterday, is entitled “The Sacred Disease.” That name derives from the fact that those who develop temporal lobe epilepsy are sometimes known to become spontaneously hyper-spiritual in the process. In fact, many scientists now believe that Joan of Arc, Saint Paul (the Apostle), and [for my Indian readers] Ramakrishna were afflicted by this ailment. (Not based on their high degree of spirituality, but rather on accounts of sensory phenomena they were said to have experienced.)

Chapter nine examines cases related to hemianopia—a situation in which one occipital lobe is damaged resulting in a kind of “blindness” in half one’s visual field. While people think of blindness as being a problem with the eyes, it’s possible to have perfectly good eyes and optic nerves and be blind (on a conscious level) due to brain’s incapacity to process the input it is receiving. (Incidentally, in his book “Subliminal” Leonard Mlodinow describes engrossing cases of people who were blind due to brain damage, but–owing to a redundant subconscious systems–they could walk around without running into obstacles.)

Chapter ten describes cases associated with delirium, a common cause of hallucinations that can be the side-effect of any number of physical problems including fever, blood sugar imbalance, and liver failure.

The next two chapters are about sleep-related sensory imaginings. Chapter eleven details cases of hypnagogic and hypnopompic imagery, which are what we see as we are on the edge of falling asleep or awaking, respectively. Hypnagogic hallucinations may be as simple as shifting shapes, or more elaborate. If you’ve gotten this far in the book without any experience that corresponds to what Sack’s is describing, you’ll almost certainly have some experience with hypnagogic images. If not, you should stop consciously counting sheep (or whatever other daydreaming you do as you fall asleep) and just watch what your mind projects. You’ll know it when you see it because you won’t be able to control the imagery (though you can distract over it with conscious thought) and—as in dreams—it probably won’t make a lick of sense. Hypnopompic images are quite different, less widely experienced, and often more disconcerting. Chapter twelve presents cases dealing with narcolepsy (random spontaneous falling asleep) and sleep paralysis, a common experience on the trailing edge of sleep in which one can’t move and which often comes with imagined sensations of a more nefarious variety—hence the widespread lore of night hags and the like.

Chapter thirteen scrutinizes cases that are associated with traumatic events from one’s past. These can involve sightings of ghosts of departed loved ones or replays (flashbacks) of the traumatizing event. This chapter, in a discussion of dissociation, also foreshadows the phenomena of out-of-body (OOB) experience that’s dealt with in more detail in chapter 14. The theme of that penultimate chapter is seeing oneself. Beyond OOB, it deals with a variety of hallucinations of oneself, including those in which one’s body appears distorted (i.e. so-called “Alice in Wonderland” Syndrome.)

The last chapter discusses hallucinations in the tactile domain, and, specifically, the most widely investigated form of these phenomena—the phantom limb. Phantom limb syndrome is experienced by amputees, many of whom can still feel the lost limb. This has resulted in nightmarish scenarios in which an awaking patient complains of an itch on the sole of his or her foot only to be shown that they have no legs from the knee down.

There are no graphics in the book, but, because it’s based around cases, it doesn’t need them for clarification of complex ideas. There are footnotes, as well as a bibliography.

I found this book to be absorbing, and I learned a great deal from it. I’d recommend it for anyone who seeks greater insight into hallucinations or unusual mental phenomena more generally.

BOOK REVIEW: The Tale of the Dueling Neurosurgeons by Sam Kean

The Tale of the Dueling Neurosurgeons: The History of the Human Brain as Revealed by True Stories of Trauma, Madness, and RecoveryThe Tale of the Dueling Neurosurgeons: The History of the Human Brain as Revealed by True Stories of Trauma, Madness, and Recovery by Sam Kean
My rating: 5 of 5 stars

Amazon page

 

Once upon a time, our knowledge of what the brain did, how it worked, and the degree to which its parts were specialized came from observing people who had brain injuries or a disease of the brain. Kean’s book examines the evolution of our understanding of the brain by way of investigations of historic cases. Looking at damaged brains is obvious not the ideal way to study the most complex system in the known universe—accidents and brain-eating diseases aren’t discriminating. Still, over time, a few conscientious [and sometimes warped] doctors and scientists pieced together important clues. From the rudimentary observation that people conked on the head often pass out temporarily, doctors began to learn about the degree to which brain parts were specialized and how changes in the brain effected beliefs, memories, and behavior.

Kean’s book is in part a history and in part a work of popular science, and the cases selected are often of interest both as history and as science. We learn about the damaged brains of kings, assassins, soldiers, adventurers, and those with more mundane jobs but no less fascinating brain trauma (e.g. Phineas Gage, one of the most well-known cases in the book, a construction foreman who had a steel tamping rod rocketed through his skull.)

It’s this historical approach that builds a niche for Kean. There have been a massive number of popular science books on the brain in recent years. (You’ll note that I’ve reviewed many of them.) While other books discuss many of the same intriguing neuroscientific phenomena (e.g. synesthesia [mixing of sense and / or mental data, e.g. people who see colors with musical notes or even with numbers], phantom limbs, epilepsy’s effect on beliefs, and the brain’s role in aberrant behavior) most of them are rooted in the mother-lode of discoveries that have come out of functional Magnetic Resonance Imaging (fMRI) and other modern technologies. Even the works of V.S. Ramachandran, which largely deal in discoveries rooted in low-tech but exceedingly clever science, are placed in the context of present-day science. (You should read Ramachandran’s book “The Tell Tale Brain” also.)

Kean’s book is complementary to the body of works on popular neuroscience. While some of those books mention the same (or similar) cases as Kean, they do so to illustrate the Dark Age origins of many of these questions. Kean delves into the intriguing details of such cases. On the other hand, while Kean is dealing in the historic, he brings in modern science on occasion to give the reader insight into what ideas have been confirmed and which overturned. That’s important as Kean is often telling the reader about the opposing theories of the day—as the title suggests.

The book contains an Introduction and twelve chapters that are arranged into five parts. The book’s organization is by brain structure and key (interesting) functions tied to those various parts. It’s logically arranged, starting with a question as crude as the skull’s role in brain injury and ending on a topic so challenging that there remains a great deal of mystery (and controversy among scientists) about it, i.e. consciousness. In between, we learn about neurotransmitters, neuroplasticity, and the brains role in sensory processing / presentation, bodily awareness / movement, emotion, belief, delusion, and memory—as well as the degree to which the two halves of our brain are independent and what severing the connection does.

The book is end-noted and has a works cited section, but it has a couple other noteworthy features. A fun feature of note is that each chapter begins with a rebus, a kind of word puzzle that relates to an anatomical part relevant to that chapter. There are also graphics in the form of both diagrams and black-and-white photos, and they are interspersed throughout the book with the relevant text (as opposed to in special sections.)

I’d recommend this book for individuals not only interested in neuroscience, but in the history of science generally. Even history buffs who don’t think much about science will likely learn a thing or two from Kean’s presentation of the cases—e.g. there is much discussion of Civil War wounds.

BOOK REVIEW: Remember When by Scientific American

Remember When?Remember When? by Scientific American
My rating: 3 of 5 stars

Amazon page

 

This book is part of a series put out by Scientific American magazine that collects articles on a specific topic of interest, in this case memory.

I’ll get straight to the point:

Pros: The style is readable and concise, and the book is well-organized and full of fascinating tidbits [Note: when I say “well-organized,” it’s clearly a collection of past articles of various types, and so there are a mix of short pieces, long-ish pieces, and an interview or two. However, these inconsistent “chapters” are placed in sections in a logical fashion. Furthermore, I expected much more repetitiveness from this type of collection than there was.]

Cons: First, the Kindle version that I read had lots of typos, and they were systematic typos. [Fun fact, considering this is a book on memory. My memory was that this book had typos throughout, but when I looked back through to review it, I noticed it was only some chapters, but—influentially—including the last.] By “systematic typos” I mean the same characters were replaced throughout with the wrong character(s.) While this isn’t the kind of typo that leads to confusion, it’s the kind that makes one say, “Did you really not have anyone look this over after it was machine-converted, you lazy …?” Second, because it’s a collection of magazine articles, one might see a piece from recent years right next to one from the 1990’s. This wouldn’t necessarily be anything to concern one, and might even be a positive. However, once one has seen the aforementioned laziness, it makes one wonder whether half the information isn’t outdated.

The 30 pieces that make up this collection are divided among seven sections to provide a logical organization and progression of the material.

Section 1 explains what memory is and why it seems to work so well in some cases but so poorly in others.

The second section explores the neuroscience of memory and how the brain turns experiences into memories.

Section 3 offers insight into the connection between learning and memory. This describes some fascinating discoveries on the importance of white matter (not the cells that store the memories, but the ones that connect those that do) and the role of sleep.

Section 4 is where it really gets interesting. This section investigates amnesia, hypnosis, and déjà vu.

The fifth section considers a few of the many ways that memory can fail. Besides discussing how false memories are created and attempts to erase traumatic memories, the section also explores the connection between emotion and memory.

Section 6 answers why memory gets worse with age, with discussion of a few of the methods for reducing this tendency.

The last section describes some of the methods used to improve memory. Here, I will offer the same warning as I did for the last review I did on a book of this topic (i.e. “Memory: A Very Short Introduction”), which is to say that if this is your primary purpose for buying the book, you probably want to look for a more specialized book. (Where the AVSI book was a cursory summation of proven techniques, this one focuses on the science of the moment [e.g. experimental medicines and blueberries] and not well-established techniques.)

The graphics are those from the magazine, and, therefore, tend to be detailed and “slick.” This can be a disadvantage when reading on a base model Kindle, such as mine. Even with the graphics expanded, the font is tiny and hard to read. Also, the color graphics on a black-and-white device would likely be clearer as simple line diagrams rather than complex computer renderings. However, most of the articles have little to no graphics, and so it’s not a problem that comes up with great frequency.

I’ll compare this book with the Oxford University Press “A Very Short Introduction” on the same topic that I just reviewed because they are clear competitors. This book covers a broader range of topics, including some intriguing ones such as: hypnosis and memory, déjà vu, the role of fitness on memory, and more detailed information about the connection between sleep and memory. In other words, this book is full of the latest (at the time) research of a nature intended to attract popular science magazine readers. However, the AVSI book is more concisely arranged to get a neophyte up to speed on memory without offering extraneous information. I suspect the AVSI book will age better. The Scientific American book has a fair amount of current events reporting that may be overturned (if some of it hasn’t already been) by subsequent research. The AVSI book was much more easily readable on my Kindle.

I found this book to be interesting and informative—though not without significant flaws. Overall, I’d recommend it for those wanting to learn about the research of recent decades on memory.

My Vipassana 10-Day Experience: No Solidified Gross Sensations, No Gain

woman-pointing-at-herself6

It’s 4:45 in the morning and I’ve been sitting on my cushion at the Dhamma Setu Vipassana Meditation Center in Chennai, India for a quarter-hour. It’s day one, and I’m observing my breath as it comes in and out through my nostrils—at least for seconds to minutes at a time before I have to coral my mind back from some random tangent. This breath exercise (ānāpāna-sati), I will soon learn, is a preparatory exercise used to reign in the mind enough so that actual Vipassana meditation can be introduced on the middle of the fourth day. In eleven days, I’ll be in the closing session of the course.

 

There are several approaches to Vipassana meditation taught throughout the balance of the course, but the gist is the same for all of them. One rotates one’s awareness throughout the body systematically observing sensations. As one does this, one works toward equanimity, a calm and quiet state of mind in which one neither covets pleasurable sensations nor shuns unpleasant sensations. The idea is to train the deepest level of the mind to not habitually lunge one toward pleasure or away from displeasure.  (FYI: displeasure = pain.  At least for a novice, such as myself, there is a fair amount of pain involved in sitting still for such long periods. It’s generally referred to a solidified gross sensation to differentiate it from the uniform and subtle sensations that one may feel in the parts of the body that aren’t in agony. I joke about it here, but there’s good reason to train oneself to not think in terms of pain, and the negative connotation the word evokes.)

 

At that course’s beginning, I knew a little about Vipassana from research, including reading the book “Equanimous Mind,” one man’s account of his experience in the course. For example, I knew that most people who quit, leave either on day two or day six. At the time, I didn’t know why, but would learn soon enough. It’s nothing about those two days, but rather the days that precede them. Day 1 seems to last forever, and it’s easy enough to discern why it might give students trouble. When one gets through day 1, an optimist says “yeah, I can do this because I’m through the first day” but a pessimist says, “I just barely made it, I can’t do this.” Day 5 is when the strong commitment (adhiţţhāna) is added, which means that one has three one hour sessions during which one is to commit to not changing one’s posture for the whole session. No opening eyes, but—more challengingly—no unfolding /refolding one’s legs.  This commitment to not changing posture steps up the difficulty of the course to another level.

 

It should be noted that one can opt to sit in a chair. However, that introduces an entirely new challenge—drowsiness. During the long sessions, when I’d get up to walk the lymphatic fluid out of my legs, there were usually two people in a straight-spined meditative position and six to eight who looked to be sound asleep.  (Drowsiness was one reason that I didn’t sit in a chair. I’m prone to get sleepy enough during meditation, especially in a complete absence of caffeine. The other reason was that I’ve not found chairs to be more comfortable for long-sits of meditation. Once your bony parts start pressing into the chair, one begins to wish one was cross-legged on a cushion. One can make the chair more comfortable by placing padding wherever it’s uncomfortable, but eventually one has a virtual La-Z-boy and the drowsiness factor becomes all the more problematic.)

 

With respect to these strong commitment (adhiţţhāna) sessions, I didn’t make it the full hour without moving on the fifth day–or any day until day 10, in fact. However, I don’t count this as a failure, because I did give it my all. I say that based on the endorphin-induced euphoria, simple hallucinations, and a proprioceptive form of Alice-in-Wonderland Syndrome that I experienced from toughing it out past mere discomfort. I’ll get to what that all means, but for now suffice it to say these happenings were symptomatic of sitting still through the period in which the pain came, grew, and then started to numb out.

 

In fact, these trippy experiences may, sadly, have been one reason why it never occurred to me to want to leave around day six. While I tried not to get caught up in them, these experiences were fascinating. I could see why day 2 presents a challenge to so many, but day 6 was a hoot, relatively speaking. The second most challenging day for me was day 8, because I’d reached a plateau but I didn’t yet feel myself in the homestretch. But by day 8, who’s going to leave? You’ve gutted it out that long, and are almost done. For those concerned about whether they can make it to the end, I can honestly say that I never seriously considered quitting. It’s not that hard to get through the 10 days, as long as one isn’t too addicted to comfort and communication.  That said, I wouldn’t offer a wholesale recommendation of the course as many do, but rather recommend it on a case-by-case basis. If you’ve done no meditation whatsoever, this is the meditative equivalent of going from couch-sitting to training for an ultra-marathon overnight. If you think you can’t get through nine days of silence–without no phones or books, maybe you can’t, and you should probably reevaluate your life.

 

I mentioned some of the unusual experiences that I witnessed during the course, and I’ll get into that a bit more. I should preface this by saying that one shouldn’t get caught up in these trippy happenings for reasons I’ll elaborate upon below, but they may happen so it’s worth being ready for them. Here’s a list of the unusual events I experienced:

 

-Extreme relaxation / lethargy: a little off topic, but between sessions on day 1, I noticed that I couldn’t be bothered to shoo away a fly that kept buzzing around my head with random touch downs. I don’t know how long I walked with the fly buzzing over me before it struck me that this was unusual. This was before Vipassana proper had been introduced, so it didn’t yet seem apropos.

 

-Olfactory hallucination / vivid scents: on day 2 I witnessed a distinct smell from my elementary school days (i.e. a mix of cleaning solution and milk cartons?) that theoretically could have originated at the Dhamma Setu, but which was quite probably an olfactory hallucination. It was short-lived and I never smelt it again. I did later experience an intense smell of flowers inside the meditation hall. This may well have been an actual scent as there were many blooming flowers there. These vivid scents were also short-lived.

 

-Endorphin-Induced Euphoria: on days 4 and 5, I experienced this as an almost intoxicated feeling. [Endorphins are the body’s indigenous pain-killers.] As drunks find unfunny things funny, so did I—including the pain in my legs and back. I wondered if anyone would be distracted by my occasional giggle-fits, but I think they were much more subdued than I suspected from my vantage point. Just like I’ve thought I was talking in my sleep in the past, only to be told that it sounded more like faint and indistinct whimpering. On day 6, I experienced a more sophisticated (not drunk-like) form of euphoria that expressed itself as a feeling of “oneness.” I’ve read about feelings of oneness being attributed to a form of transient hypo-frontality—i.e. a shutting down of the parts of the prefrontal cortex (PFC) that track the self / other distinction. There may have been more happening than endorphins (and other neurotransmitters) involved in that happening.

 

-Lifting sensation: This was the single most awe-inspiring experience that I was party to. For those unfamiliar with seated meditation, one of one’s chief enemies in long meditation sessions is a proclivity to slump. Slumping translates into agonizing back pain and labored breathing. So whenever one catches oneself slumping, one has to straighten one’s back. [If you wonder why a meditator would pretzel up his or her legs in full lotus (padmasana), the alignment of one’s legs helps one maintain a straight spine.] At any rate, on day 6 I experienced the feeling that I was being lifted up straight and it became effortless to maintain a straight back for the rest of that session—as if an outside force were doing the work. This lifting sensation wasn’t like being lifted by a person, but rather like the action of a “tractor beam” from the world of sci-fi. While I have some inkling of the causes of much of what I experienced based on the science of the human body, explanation of this “lift” is harder to come by. I did read an account in Oliver Sacks’ “Hallucinations” by a woman who suffered from migraine-induced hallucinations and Alice-in-Wonderland Syndrome that was a spot-on description of what I experienced as well.

 

-“Visual” [closed-eye] simple hallucinations: I didn’t experience anything even close to the what people usually think of as a hallucination—that is, there was nothing that could be confused with reality. I wouldn’t have even known to call these images hallucinations if I hadn’t been reading the aforementioned Oliver Sacks’ book. Mine were quite close to what are described as hypnogogic (falling asleep) hallucinations in the Sacks’ book. This makes sense. While I wasn’t drowsy at the time, my brain was probably in a pretty similar state of relaxation. Mostly, these were moving shapes that formed and dissipated in a field of black-fringed purple.  On day 7, there were more complete visuals—mostly of partial faces, usually with mouths wide open. I took this as my subconscious mind’s comment on the noble silence. (On the noble silence: from about 6pm on day 0 [orientation afternoon] until the morning of day 10, one isn’t allowed to talk or in any way interact with / acknowledge anyone except to direct questions to the teacher or staff. Whether one has questions or not, one will speak at least a few words to the teacher every day or two when he / she reviews one’s progress. For some, this may be the single biggest challenge of the course, but I’m a hardcore introvert and could do ten days of silence standing on my head.)

 

-Tactile Alice-in-Wonderland Syndrome: Alice in Wonderland Syndrome usually refers to a visual form of hallucination in which things appear a great deal taller, smaller, closer, or farther than they actually are. What I experienced was a great deal less whacky and traumatic than that. With eyes closed, I felt a distortion of the size and shape of my arms. Sometimes my arms felt like they were six-foot long from deltoid to fingertips, and sometimes the same points seemed to lie a foot and a half apart. Needless to say, those are both distortions of the actual length of my arms.

 

-Inexplicable Beatles’ Music: On day 8 my mind bombarded me with music from the Beatles for a little while. In particular I heard “Sgt Pepper’s Lonely Hearts Club Band”, “Lucy in the Sky with Diamonds”, and “All You Need is Love,” or parts thereof, in high fidelity. Now, while this is fine music, it’s not music that I’ve listened to recently nor have I listened to that album a great deal. When I was growing up, there was a copy of “Sgt Pepper’s…” at home, but I’ve only periodically heard these songs on the radio since. The experience was monotonous because only the parts that I knew the words to (i.e. the choruses) replayed on a loop, but the music and voices were crystal clear as if I were listening to the album.  Given the lack of personal relevance, I can only imagine that my subconscious thought this is the kind of music a person meditating would like to hear.

 

As I said, by about day 8 I’d hit a plateau. The aforementioned odd experiences were petering out, particularly when I did as I was supposed to do and gently returned my mind to the task at hand. Yet, the practice wasn’t getting any easier or smoother. I still had the same dead spots—areas that I could observe for extended periods without even the subtlest of sensations—and I still had growing pain zones in my back and legs—i.e. starting from isolated pains, the pain would become increasingly diffuse and of ill-defined boundaries—but often no less painful.

 

Now I’ll explain my comment about not allowing oneself to become captivated by the trippy experiences. If one seeks after these experiences, not only is one missing out on the value of the practice, one is actually moving in the wrong direction by coveting an experience while impulsive craving is what one is training oneself away from through Vipassana meditation. Beyond this, seeking out such experiences is likely to be frustrating because they are products of the subconscious mind and physiological processes that are beyond conscious control. They happen when they happen, on your body’s schedule. (Note: Some people think of these as spiritual phenomena. I don’t, but—for those who do—they still won’t happen on your schedule. Ostensibly, they’ll happen on some deity’s—presumably rather tight–schedule. And—divine as they may be—they are still a distraction from the objective of the practice—and that’s not my opinion, but according to the teachers of the tradition, starting with Gautama Buddha and through to S.N. Goenka.)

 

So when one experiences such phenomena, one should do the same as one always does in meditation, quietly and non-judgementally return one’s mind to the object of awareness—in this case, systematically witnessing the sensations on one’s body. I won’t say that this isn’t a challenge. It is, because your mind is presenting you with something fascinating and new, and you’re asking it to return to a task that has become rather mundane over hours and days of practice. It should be noted, I would broadly categorize the phenomena that I experienced into two slots, one of which is things the brain does to cope with a lack of external stimulation. (The other being, things the body does to cope with unrelenting pain.) So it takes some discipline, but one should remind oneself—as one is frequently reminded during the discourses—that you are there to give the Vipassana approach a fair trial, and as fascinating as these sideshows are they are a distraction from the practice.

 

That said, these things will happen and their unusual nature may make them points of concern or confusion, and so I’ll discuss them a bit more. I have a theory about the cause of the euphoric experiences, but it requires a little clarification and background. What makes Vipassana challenging for a new practitioner—at least for me— is that in systematically rotating one’s awareness to observe sensations, one has to ignore areas that are screaming with pain while carefully running one’s attention through areas that seem completely devoid of sensation. This requires quieting the mind and especially not feeding the anxiety about one’s pain and discomfort—hence, developing equanimity (steadiness of mind.) Sitting still for an hour at a time, lymphatic fluid piles up in your lower extremities (no pump in the lymphatic system but the one of movement), over time blood circulation may be inhibited, and this lack of circulation has ramifications for the cells not being adequately nourished. So your body notices this fluid build-up (a relatively minor concern, easily rectifiable, and which will take a while to be a serious problem for most people) and sends you some pain sensations to spur you to get up and move about. When you don’t get up and walk, it turns up the discomfort disproportionate to what’s happening with your body. You still ignore it. Eventually, your body starts to think maybe a boulder fell on your legs and you’re in shock (the conscious and unconscious minds don’t talk as much as you might think, and—even if they do—let’s face it, at least the conscious mind is a big, fat liar.) It’s at this point that your body starts to emit some feel-good chemicals. (I refer to “endorphin-induced euphoria,” but it’s more extensive than natural painkillers. In reading up on the subject, I noted references to serotonin and even melatonin (yes, the skin color chemical) in addition to beta-endorphins. I wouldn’t be surprised if there was some dopamine—a reward / feel good chemical—in the mix as well. Hence, the euphoria.

 

I don’t think it’s necessary to get into the hallucinations and other effects that the mind creates in order to cope with the lack of sensory input. This is a well-studied area, and there’s been a lot written on how the mind hates the dark and the quiet over extended periods. I would recommend the aforementioned book by Oliver Sacks on hallucinations as a case in point.

 

Saving the most crucial question for last, was it worth it? In his discourses, S.N. Goenka offers three criteria by which one might evaluate whether Vipassana is worth practicing. While all three are sound criteria, I’ll focus on just one of these, which is really the bottom-line, and that’s whether it makes an improvement in one’s life. That is, does one start to be less prone to impulsively react to craving and aversion and become more equanimous of mind?

 

On this, I’ll have to say that the jury is still out. Many come out of the 10-day course calling it life-changing. I’d say that it was beneficial because I learned a meditative technique that has a sound internal logic (even if one doesn’t believe every aspect of the mechanism by which it is said to work by Buddhists—which I don’t), an established track record of benefit for many, and the feel that it’s benefiting one. However, I’m still evaluating the approach. I’ve been doing Vipassana meditation twice a day with morning and evening affirmations. Let’s face it, 10-days isn’t a long time to overhaul one’s deeply ingrained modes of operation—even sitting in meditation for 10 hours a day. I’m optimistic, and the practice sure doesn’t hurt—except for those solidified gross sensations, they hurt.
