If one has an inquisitive nature and finds oneself with a bit of time on one’s hands, one is likely to question reality eventually. What is reality? What does it mean to be real? (Yeah, just like Morpheus’s “How do you define ‘real?’”) How could we know if we weren’t in the reality we think we are? Does it matter? i.e. If we aren’t in the reality we think we are, do we have any other choice than to behave as if we are—in other words is there any hope of escaping whatever unreality our consciousness exists in?

Does the quantum world not make a lick of sense relative to the world as we know it because the ancestors who are simulating us never expected us to get far enough to investigate that scale before we crashed? And now, like the writers and directors of an unexpectedly popular and long-lived TV show, they have to find a way to cobble some convincing story together because their overlords aren’t willing to scrap a perfectly functional simulation as it’s churning out huge amounts of data. Of course most people quickly dismiss such possibilities as sci-fi, but—then again—that dismissal is what one would do if one was programmed to be psychologically pained by the idea that the lunatic shouting and running naked through the streets may have found freedom, while you–who appears to be fully successful in living life—are an automaton, a slave pure and simple?

Philosopher Jan Westerhoff provides a brief survey of the many ways reality has been questioned over time and what evidence proponents cite—or, if not evidence per se, what inexplicable phenomena at least make the possibility seem feasible. The book consists of just four chapters. The first chapter offers a context by discussing dreams and simulations. Dreams are one of humanity’s first sources of doubt about reality. This was most famously summed up by the Taoist philosopher Zhuangzi’s quote “Now I do not know whether I was then a man dreaming he was a butterfly, or whether I am now a butterfly, dreaming I am a man.” The simulation hypothesis suggests that societies eventually develop a capacity to run extremely advanced simulations that would feel very real, and, furthermore, the proliferation of such simulations would make it much more likely that we are in one than in a real world.

The next three chapters examine three subjects where reality is taken for granted, but which each face challenges. The author starts with the most basic component of reality, matter. If you ask someone how they know the world is real, they might just knock on wood or kick a stone. Of course, that response only goes so far because there are a lot of entities we consider real that aren’t made of matter (e.g. is an economic recession real?) and so it’s definitely not a complete way of looking at the topic. There’s also the fact that all this hard and solid stuff we experience is mostly empty space. In this chapter, Westerhoff spends much of his time examining the basics of quantum mechanics, and the quantum strangeness that has put it in the minds of many that the world is probably not what we think it to be.

Chapter three explores the reality of a person. This is where people have the hardest time questioning reality, because most of us are quite certain that we exist. Descartes statement of: “I think, therefore, I am” nicely sums it up. But is there a place associated with personhood, or is it an emergent property? If it has a point of origin, where is it? Westerhoff describes the famous rubber hand experiment that shows that the connection between mind and body is more illusory than we think. He discusses many of the syndromes that challenge our intuitive beliefs about what it means to be a person, e.g. Cotard syndrome, in which individuals firmly believe that they don’t exist. (Note: this topic—at least the scientific dimension—is covered in detail in Anil Ananthaswamy’s book “The Man Who Wasn’t There.”)

Chapter four explores whether time is really what we think it is, and what it feels like to us. A lot of this chapter takes up findings about free will. A famous study in the neurosciences showed that before people make a decision at a conscious level, there is activation of subconscious parts of the brain such that what feels like a decision freely and consciously made is actually already made before the consciousness ever becomes aware of it. This study, now overwhelmingly validated by replication, presents a major challenge to our notion of free will—which isn’t to suggest we’re necessarily being fed a decision from some mysterious elsewhere but if some combination of our limbic and enteric nervous systems are making decisions without conscious input, then what is the nature of freedom in free will?

The book has an interesting Conclusion that gives the reader a map to consider the various ways reality might exist (or not.) This isn’t a dichotomous question—i.e. it’s not necessarily a matter of the world is real or it’s not. Instead, it can be thought of more as a continuum between everything is real and nothing is real with various way-points in between such as “I am all that is real” or “Everything is real, but me” and various ways of considering how some of the world might be real while some of it is not. Among the latter models, the relevant factor maybe consciousness (i.e. conscious may be unreal or maybe it’s the only thing that’s real.)

There are a number of graphics used to support the text, most of these are photographs and artworks, but some are diagrams. There is a “References and Further Readings” section in this book that is more substantial than most of the ones I’ve seen in AVSI (A Very Short Introduction) series books. It’s organized by chapter.

I’d recommend this book for anyone interested in the topic. I think the author does a great job in a small space of introducing various conceptions of reality. He draws on well-known works of film and literature to help clarify issues, and provides many thought-provoking ideas. It’s readable and doesn’t get bogged down in minutiae.

A Wrinkle in Time (A Wrinkle in Time Quintet, #1)A Wrinkle in Time by Madeleine L’Engle
My rating: 5 of 5 stars

Amazon page

 

The Murry family feels mopey. There are a number of run-of-the-mill factors in the family malaise. Meg, the story lead, doesn’t fit in in school, and is frequently in disciplinary trouble. Her younger brother, Charles Wallace, is thought to be mentally deficient because he doesn’t talk to strangers, but he is—in fact—a genius. However, the big cloud hanging over this family’s head is that their father hasn’t been heard from for a year. He isn’t the type of father who goes out to the store for cigarettes and never comes back. Instead, Alexander Murry—Meg’s dad—is a loving father and husband who happens to be a renowned scientist who sometimes does work for the government. Even when he’s off doing top-secret work, however, he checks in with his wife and kids on a regular basis, but now there’s been no communication for months. The townspeople both pity the Murrys and think them to be living in denial because they maintain that Alexander Murry will soon come back.

While the book begins with a real world premise and feel, it soon becomes apparent that things aren’t what they seem–at least not around the Murry household. (Things not being as they appear recurs as a theme throughout this book.) Our first inkling of this unusualness comes when we realize that Charles Wallace isn’t only a genius and preternaturally mature, he also appears to be psychic. Events really turn strange when Meg’s mother, Katherine, goes out to investigate a noise and comes back into the house with an old lady who—surprise of surprises–Charles Wallace knows, a Mrs. Whatsit. And, as he seems to do with everyone, Charles Wallace begins talking to the old lady as if he were a sage old man.

The story follows the adventures of Meg, Charles Wallace, a boy named Calvin O’Keefe as they go with three mysterious visitors (one of whom is the aforementioned Mrs. Whatsit) in search of Alexander Murry. While O’Keefe is a popular kid and a jock, he doesn’t really feel he fits in. In that way, he’s a counterpoint to Meg. Meg doesn’t fit in and it gets her in trouble. O’Keefe pretends to fit in, but has angst about it. Furthermore, O’Keefe seems to have some sort of supernatural ability—perhaps not of the level of Charles Wallace, but enough to exacerbate his feeling of being an outcast among his own family and community. It’s Calvin’s feeling that he’s at home with the Murrys that accelerates his inclusion in the story.

The sci-fi elements of this book, as with many other great works of children’s science fiction, facilitate the teaching of simple moral /ethical lessons. Don’t rush to judgement about people—Aunt Beast is one of the most endearing characters of the book. Fitting in is not all it’s cracked up to be, and if everyone were the same, what a dreary existence life would be. And, ultimately, love conquers all.

I’d highly recommend this book for children and adults alike. The story is highly readable owing to narrative tension and mystery.

BOOK REVIEW: Going Solo by Roald Dahl

Going SoloGoing Solo by Roald Dahl
My rating: 5 of 5 stars

Amazon page

 

This is the second installment of Roald Dahl’s autobiography, and it covers the period from the time when the famous children’s author left home to work Shell Oil in East Africa, through his adventures as a pilot in the Royal Air Force (RAF) during World War II, concluding with his return home to England. In short it covers the earliest years of his adulthood, before he wrote such classic books for children as: “BFG,” “Matilda,” and “Charlie and the Chocolate Factory.”

In fifteen chapters, Dahl discusses his mysterious shipmate on the ship to Africa, a lion attack, an unwanted visitor in the form of a green mamba snake, and Dahl’s early experience of the war before he became a pilot. Becoming a pilot represents a shift in the book’s tone. From that point, it’s more of a war story, with the higher tempo of life and death situations that entails. That isn’t to say there’s no life and death in the first part, but it’s more quirky and humorous. In the chapters about his life as a pilot, Dahl describes crash landing in the desert and his subsequent recuperation, how he was posted to Greece where the German Air Force had a fleet of planes that made Britain’s look minuscule by comparison, and then his squadron’s move to Palestine to what would be his last battle-filled days before he was relieved from flight operations and sent home.

The stories throughout are as well crafted, as one might expect from a master storyteller. Dahl follows the advice (often-attributed to Elmore Leonard, but which has been around for decades in some words or another) to, “…leave out all the parts readers skip.” There is a tension throughout the book. It’s a much different approach than the previous volume, “Boy” which plays off the dramas of the adult-child interaction.

There are many graphics throughout the book, mostly black-and-white photos, but also maps and documents, but no other ancillary matter.

I’d highly recommend this book. If you want to know how to write a memoir that people will read, this is how it’s done. Dahl doesn’t try to take us from cradle to grave. He’s happy giving us the parts we won’t skip.

BOOK REVIEW: Crossing the Heart of Africa by Julian Smith

Crossing the Heart of Africa: An Odyssey of Love and AdventureCrossing the Heart of Africa: An Odyssey of Love and Adventure by Julian Smith
My rating: 5 of 5 stars

Amazon page

 

This book tells two tales in parallel, connected by one theme: travel for love. The author, Julian Smith, recounts the experience of Ewart Grogan, an English explorer whose life straddled the 19th and 20th centuries. Grogan traveled the length of Africa from South to North and recounted his experience in a book entitled “From Cape to Cairo.” The purpose of his grand endeavor was to prove his worth as man. Grogan was in love with a woman whose family was of higher station, and he believed that if he could only do what had never been done before, then the objections to his “marrying up” would dissolve.

The other story is Smith’s own attempt to retrace Grogan’s route across the length of the continent. While Smith doesn’t have to prove his worth, his motivations are more complex and tied up with his engagement to be married. Maybe Smith’s motivation is best summed up as a desire to prove to himself and / or his fiancé that he had sufficient commitment and fortitude to get him through rough times—a characteristic relevant to both marriage and crossing some of the world’s least developed countries.

Of his own admission, Smith’s journey was to be far less arduous than Grogan’s by virtue of the fact that he’d be traveling by taxis, motorcycles, buses, and ferries. Grogan and other 19th century explorers were subject to hazards far graver and more ever-present. For one thing, in Grogan’s day virtually everybody who spent any significant time in Africa got malaria. It wasn’t a question of if but when and how seriously. Even if you escaped malaria, there were myriad other tropical diseases to bring one to one’s knees. Next, there was the tribal environment in which one would travel through dozens of tribal territories, all of whose chiefs expected tribute and many of which were outright hostile. For Smith, rule of law was present in some form or fashion along most of his route, such that no one could just murder him and get off scot-free. There was also the risk of crew desertions that could cripple an expedition. Traveling parties had to carry huge amounts of goods from surveying equipment to gifts to medicines to food stuffs. Still, they had to obtain many of the party’s needs along the route. Among other things, this meant hunting animals that weren’t as docile as livestock. Anything less than an instant kill meant having to trudge into tall grass after a wounded creature that had a far greater killing capacity at close range.

This isn’t to say that Smith’s journey was adventure free. Anyone who has traveled in Africa knows that getting from place to place remains a slow and exhausting process. And many of the things that undermined Grogan’s trip also undermined Smith’s, e.g. the author suffered extended fever. But the most devastating factor for Smith’s travels was the fact that parts of Sudan were lawless and a brutal war was being fought. While Grogan barely managed to drag himself through the swampy landscape, Smith was unable to proceed overland because of the conflict. In telling of his travels, Smith discusses many of the dilemma’s that traveler’s face today (e.g. to give people money or not, how to contend with bureaucrats.) Among the travels that modern-day readers might be interested in is Smith’s visit to a gorilla sanctuary.

I enjoyed this mix of travelogue and history. The book gives one insight into the changing nature of the world and, particularly, what was once called the Dark Continent. [Note: while that may sound either racist or awash in a negativity bias, I’ve read that the reason it was called that was that when the 19th century explorers were traveling through much of the continent was unmapped, i.e. blacked out.]

I’d recommend this book for anyone who is interested in travel in Africa—past or present.

BOOK REVIEW: Hapkido by Scott Shaw

Hapkido: Korean Art of Self-DefenseHapkido: Korean Art of Self-Defense by Scott Shaw
My rating: 4 of 5 stars

Amazon page

 

When I picked up this book, all I knew about Hapkidō was that it was a Korean martial art, that it wasn’t a sport like its more famous martial cousin—Tae Kwon Do (TKD), and that it was a more comprehensive art (grappling as well as striking) than TKD. I grabbed it because at least one of these mental reductions proved only partially correct and I wanted to know what else I might be getting wrong. In the first paragraph, I learned that Hapkidō was heavily influenced by / a descendant of Daitō-ryū Akijūjutsu. (If that art sounds vaguely familiar, it’s because it was also a big influence for its most famous student, Morihei Ueshiba—i.e. the founder of the Japanese art Aikidō.)

This book is tiny. It’s an overview of the art in less than 100 pages (and, as is common with martial arts books, at least half the space is devoted to photos.) So the first thing a reader might want to be aware of is that you’ve probably read newspaper articles with higher word counts than this book. I’ll leave it to the reader to determine whether that’s a good or bad thing.

The book consists of five chapters, but the last chapter accounts for the majority of the page count (but not the word count.) The first two chapters are histories. The first offers an overview of Korean martial arts situated in the context of national events of the time. The second chapter is a history of Hapkidō and gives one insight into Daitō-ryū Akijūjutsu and how it came to influence the Korean founder of Hapkidō, Choi Yong-Sul.

Chapters 3 and 4 examine aspects of the art that one might call “pre-basics” for lack of a better term. As ki (i.e. life force / energy, those familiar with Chinese arts might know it as “chi” or “qi”) plays a central role in the art, Chapter 3 discusses ki and describes breathing and meditation practices that are used for building energy. Chapter 4 describes break-falls and the art’s one posture / stance (a natural posture.)

Chapter 5 describes, and presents photos of, basic defensive moves of Hapkidō. There are five sub-sections that explore, respectively, the following types of techniques: disengagements (i.e. breaking away from an opponent who has seized one), joint locks, throws, punch defenses, and kick defenses.

I found this book to be concise and informative. If one is seeking a detailed overview of the art, one might want to look elsewhere. However, if one is just trying to figure out what Hapkidō is all about, it should serve you well. I doubt that an experienced student of the art would get much out of this book as it’s just the bare bones. Not everybody is looking to delve into the minutiae.

BOOK REVIEW: Tai Chi Chuan Classical Yang Style by Yang, Jwing-Ming

Tai Chi Chuan Classical Yang Style: The Complete Form QigongTai Chi Chuan Classical Yang Style: The Complete Form Qigong by Yang Jwing-Ming
My rating: 5 of 5 stars

Amazon page

 

This book is one stop shopping for students of the Yang Style Tai Chi Chuan Long Form (i.e. 108 forms.) That’s not to suggest that it only describes the sequence of that form. It does that, but it also offers lessons in the history of the art, explanations of chi and qigong, and elucidation of the fundamentals of the art.

The book is divided into four parts. Chapter one examines the history of this martial art and places Tai chi chuan in the context of Chinese martial arts as well as the Yang Style within the context of Tai chi chuan. The nine sections of the first chapter also explore Tai chi chuan as a means to healthy living, and provide guidance to students on how to go about taking up the practice.

Chapter two consists of five parts that delve into the concept of chi (qi), or energy. This section mixes together mythology of traditional Chinese theory on chi with scientific explanations where science has something to say on the matter.

The third chapter describes the 13 postures of Tai chi chuan, which are a set of fundamentals that feature prominently in the martial art. This is a relatively brief section and is where the book becomes photo intensive.

The fourth chapter offers students guidance about the unarmed element of Yang Style of Tai chi chuan. While the capstone of the chapter is a systematic walk through the Long Form, there’s also coverage of some Yang Style fundamental movements as well as presentation of meditation practices taught in the system. It should be noted that this book doesn’t cover the sequence of the Yang Style Short Form (a.k.a. 24 Forms, or the Beijing Standard Form.) (I mention that because that’s the most popular form in the world and many students may want to learn about it specifically. This book offers many insights into the minutiae of the component forms, but doesn’t describe it as a sequence.) There is a fifth chapter, but it’s only a brief conclusion.

With respect to ancillary matter, like most martial arts books, it’s graphic-intensive. The bulk of the graphics are photos that are used in chapters 3 and 4 to clarify the movements and postures. Said photos have arrows and other figures drawn onto them to help clarify the movement involve. There are also a few line diagrams and maps, and chapter 2 has a many scientific photos, diagrams, and anatomical drawings.

There are three Appendices. The first provides a list of the forms of the Yang Style Long Form. The second is a glossary of the many Chinese terms mentioned in the book. The final Appendix provides information about the DVDs that are available to be used in conjunction with the book (there are markers throughout the book to provide suggestions of when students should turn to the video lessons.) There are end-notes of cited material, but I read the Kindle edition, and most of these were unavailable because Chinese characters didn’t convert to the electronic format. This was no big deal for me because I couldn’t read the Chinese reference material anyway, but if you read Chinese, you might opt for the hard copy of the book.

I learned the Yang Style short and long forms several years ago, and bought this book to provide some background and technical guidance. I found the book to be interesting and informative, and would recommend it—particularly if you’ve learned the Yang Style (but one may find the early chapters interesting even if one hasn’t.) The author uses a number of entertaining and educational stories and the book is readable and insightful for students of all levels.

BOOK REVIEW: The Circle by Dave Eggers

The CircleThe Circle by Dave Eggers
My rating: 5 of 5 stars

Amazon page

 

In Eggers’ novel, the Circle is a technology giant that looks a lot like Google + FaceBook + PayPal + Twitter all wrapped together under one corporate roof. Mae Holland, the book’s lead, is a young woman hired into the firm owing to her close friendship with a college roommate turned high level executive at the Circle, Annie. Even though Mae is brought in to work what is called “customer experience” (i.e. customer service) doing seemingly tedious work, Mae is in hog heaven. She left a job doing tedious work in a depressing environment with minimal support, and so this job personalizing boilerplate responses in a fascinating place with the opportunity to move up is a dream. The Circle is a utopian workplace where engineers are given free rein to experiment, where great minds and performing artists come to hang out, and where one gets handsomely rewarded for playing on one’s social media at work. All one needs to thrive at the Circle is a sharp mind and a willingness to accept that one’s days of privacy and solitude are behind one.

The Circle is the dystopia that some would say we are on the cusp of and others think we’ve already plunged into. It’s not Orwell’s gray dystopia of brutal state force. Neither is it Huxley’s bright and shiny dystopia of drugs and free loving. It’s a dystopia in which people willingly give up all privacy and negate the need for a neo-KGB by posting every idiotic thing that they do directly to the worldwide web. However, as in Huxley’s “Brave New World,” we see that the most nefarious character isn’t necessarily the most dangerous. The Circle is headed by an executive trinity. There’s the tech genius who we know little about until the book’s end–except that his life runs contrary to what the Circle seeks in its employees in that he’s fiercely private to the point of being mysterious. There is Tom Stenton who is the face of greedy capitalism, a loathsome character in every way imaginable. However, the real danger comes from the likable–and seemingly reasonable–Eamon Bailey who’s an idealist who thinks that people can perfect if they have no shadows in which to make mischief.

Mae is introduced to us as a likable character. She’s a hardworking but human girl next door. When we are introduced to Mercer, her ex-boyfriend and the face anti-Circle-ism, we assume that she’s being reasonable in her dislike of him. Even though he sounds reasonable, she knows him. Mercer rails against this corporatized surveillance state, and initially one may not be able to tell whether he’s a Luddite or the voice of reason. As the story goes on, however, the reader is likely to like Mercer more and more and Mae less and less. But the question remains until the end whether Mae will do the right thing as she becomes aware of the full—disturbing–picture of the Circle.

I got engrossed in this book. It’s absorbing both because of good character development and an intriguing story. That’s probably why the novel was made into a film that came out earlier in the year. It’s one of those books with the readability of popular commercial fiction, but which provides some food for thought. Some of the twists you may figure out, but the book keeps one wondering until the reveals.

I’d recommend this book for fiction readers—particularly if you have any pictures on social media with a drink in your hand or bad judgement in progress.

BOOK REVIEW: Wired to Grow by Britt Andreatta

Wired to GrowWired to Grow by Britt Andreatta
My rating: 3 of 5 stars

Amazon page

 

This is one of those books that is hard to rate and review. It does a thing well, and if one is looking for a book of its strengths, it’ll serve one well. That thing it does well is to concisely and clearly summarize research in neuroscience relevant to learning new skills. If that is something one is interested in, and one hasn’t done much reading on the subject yet, this book will get one up to speed in just over 100 pages while offering insight into where to go to flesh out what one has learned.

That said, if one has read up on pop-sci neuroscience and /or self-help books applying said research, one is likely to find that this book offers little value-added while lacking the depth and narrative approach of competing works. The latter is particularly intriguing as this is a book about effective learning, and it seems clear that humans like learning through stories. However, Andreatta does little story telling beyond brief mentions of approaches she’s used in her seminars and occasional recaps of the stories of the researchers whose work she’s drawn upon. Some may find this isn’t so bad because it keeps the book compact. Story telling is page intensive. On the other hand, a lack of story-telling means that the material is a bit less prone to stick than it might otherwise be.

The author’s approach to making the material stick is to hang it on a three-phase model (learn-remember-do) and to keep it brief. Many of the chapters consist largely of bullet points, and in places the book feels like a PowerPoint handout. (I’ll let the reader decide whether that’s a good thing or not.)

The book is organized into twenty chapters arranged in five parts. (That tells one a lot about the brevity of chapters, given the book is 102 pp.) The five parts consist of: I.) an overview of neuroscientific fundamentals; II.) a description of research related to the “learn” phase of Andreatta’s model; III.) the same for the “remember” phase; IV.) coverage of the “do” phase; and V.) a section called “design” that helps the reader to apply what they’ve learned in the earlier parts to build approaches to teaching and learning.

There is some useful ancillary material. First, there are many graphics of a variety of types (pictures, line drawings, tables, and graphs) that are nicely drawn and effective. Second, there are “Your Learning Journey” sections interspersed throughout the book. These are one page or less exercises that are designed to help one put one’s learning to use. Thirdly, there is a bibliography that includes crucial reference materials divided by type: i.e. journal / scholarly research, books, journalistic / media accounts, and cited scholars. Finally, there are apparently additional resources accessible online, e.g. downloadable pdf files, but I didn’t investigate these features.

I would recommend this book for those looking for a concise summary of recent developments in neuroscience as they apply to education and learning. If you’re well-read on the subject, however, you might not find that this book delivers much extra. It should be noted that the author is speaking from an educator’s perspective (i.e. not a scientist or psychologist) and readers may find that a plus or not.

5 Neuroscience Fun Facts for Yogis & Yoginis

Posted on by

5.) IDEA: While our conscious mind feels like the sum of our mental world, in fact, it’s the tip of the iceberg of mental processes. Our decisions and actions are guided to a large degree by happenings below the waterline.

INTRIGUING EXAMPLE: In one study, interview subjects were randomly assigned to hold either iced or hot coffee. No attention was drawn to the coffee and it was set up as a mere accident of happenstance (the HR person directing the interviewees had her hands full.) The coffee was retrieved before the subjects made handshakes with interviewers. Unrelated to their verbal responses, those who had held the iced coffee were disproportionately described more in terms suggesting a cold personality (e.g. calculating, devious, etc.) and those who had held hot coffee were credited with a warmer personality.

RELEVANCE: Get your hands warm before you start making corrections.

REFERENCE: The coffee study is discussed by David J. Linden in his book Touch. However, there are many books on this topic, several that I’ve reviewed. In particular, I can recommend Eagleman’s Incognito and Mlodinow’s Subliminal.

 

4.) IDEA: Emotions play a crucial role in decision-making. We aren’t nearly so rationale and calculating as we think ourselves to be–particularly when there is uncertainty in the mix.

INTRIGUING EXAMPLE: Giovannni Frazzetto’s book describes cases of patients with lesions in their medial prefrontal cortexes who would deliberate ad nauseam and still couldn’t reach a decision.

RELEVANCE: This is why we don’t silence or stamp out emotions, but rather watch them dispassionately while avoiding a mental drift into a frenzy of illusion building.

REFERENCE: The Frazzetto book I referenced is: How We Feel, and it deals with anger, guilt, anxiety / fear, grief, empathy, joy, and love.  However, the patients described in his book were those of Antonio Damasio, and so you may want to check out Descartes’ Error, which I’ve heard good things about, but haven’t yet read.

 

3 .) IDEA: Experiences once thought to be supernatural, mystical, or fraudulent are increasingly being understood in scientific terms.

INTRIGUING EXAMPLE: For some, an Out-of-Body-Experience (OBE) is an impossible flight of fancy, while for others it’s a mystical / transcendent state beyond the physical realm. However, in recent years scientists have not only confirmed that people have these experiences, they’ve come a long way toward understanding such occurrences by actually inducing them via electrodes applied to the right angular gyrus. It seems that area of the brain is responsible for integrating sensory information from various senses, and its disruption creates an illusion of one’s consciousness floating outside the body.

RELEVANCE: As many have wisely advised, don’t spend a lot of time chasing siddhis–not only might it stunt your growth toward the ultimate goal, it might just be running after tricks of the mind.

REFERENCE: I highly recommend Anil Ananthaswamy’s The Man Who Wasn’t There. The book looks at the various ways in which “self” has been defined (one’s memories, one’s body, etc.) and it shows how neuroscience has learned a thing or two about the various dimensions of self, and how none of them fully defines an “I.” (i.e. The Buddhist conception of the self as illusion might turn out to be not far off the mark.)

 

2.) IDEA: Our brains can be rewired through practice and training. The property is called neuroplasticity, and it’s often described by the verse: “neurons that fire together, wire together.”

INTRIGUING EXAMPLE: You may have heard about  how London taxi cab drivers develop an enlarged hippocampus, which helps them meet the vast spatial memory needs required of the job. However, an even more fascinating example may be how some blind people have developed a capacity for echolocation–i.e. their mind registers changes as sound bounces off walls, curbs, and other obstacles.

RELEVANCE: One takes advantage of neuroplasticity when one works to be more kind and compassionate by recognizing and changing one’s behavior patterns.

REFERENCE: Fascinating reading on the topic can be gleaned from Kathleen Taylor’s book Brainwashing, but the most widely-cited book on the topic may be Norman Doidge’s The Brain That Changes Itself.

 

1.) IDEA: We have neural circuitry that predisposes us to spiritual belief and inclinations toward the sacred.

INTRIGUING EXAMPLE: The evidence suggests that it’s not so important who or what you believe in, but the more positive the message the better. People of religion have demonstrated both better and worse health outcomes–all else equal–and it seems linked to whether you have one of those smiting gods or a more compassionate one.

RELEVANCE: Belief and surrender–religious or secular–can play an important role in one’s personal development.

REFERENCE: Newberg and Waldman’s How Enlightenment Changes Your Brain deals with these issues in detail.

This book examines the role of the nervous system in movement and bodily activity. It describes how one’s body is able to perform extraordinarily complex maneuvers that we often take for granted because they feel effortless. It investigates some of the ways in which the interface between body and brain go awry, as well as the various effects this can have. It also offers insight into how we can be deceived because we are experiencing the world less directly and more through the shaping activities of the brain than we feel is true.

The book contains ten chapters, plus a little forward and back matter. The first chapter is entitled “the body mandala” and it provides an overview of how the nervous system can be thought of as a series of maps layered upon maps that routes various input from outlying areas to the brain and commands from the brain to the outlying areas. A “mandala” is a symbolic representation of the universe [from Hindu and Buddhist traditions], and this notion is repeatedly revisited throughout the book.

Chapter 2 explores the mapping of the homunculus and its ramifications. If you’ve ever seen a 2-D or 3-D image /model of a human being that has gigantic lips and hands and disproportionately small torso and thighs, you’ve seen said homunculus (as the term is used in neuroscience.) The reason it’s scaled this way is that body part size is reflective of space in the nervous system dedicated to said parts and not their actual size. If you’ve ever seen one of those maps–called cartograms–in which the size of a country reflects a statistic, say, population (thus India, China, and Singapore are much larger than their physical size, but Canada is much smaller than its), you get the drift. This chapter also answers the question everyone wants to ask (and many do) which is “why–if the lips are so large because of their dedicated territory in the brain—are the genitals unexpectedly small in the homunculus?

Chapter 3 describes how body maps can be in conflict and what effect this can have. It talks about why people who lose weight often still feel fat and move in ways that are not reflective of their actual figure. It also gets into anorexia (and the lesser known bigorexia) which reflect mismatches between perceived body image and actual body schema.

Chapter 4 investigates a fascinating phenomenon in which visualization can often result in strength and performance gains. Said gains aren’t on the same scale as among those who actually exercise or practice, but the fact that one can make gains without moving a muscle is certainly intriguing. Of course, the takeaway is that one can get the best of both worlds by augmenting physical conditioning and practice with visualization—one has a more finite number of feasible physical training hours in a day (i.e. there are diminishing returns on physical training at some point.)

Chapter 5 is the first of two chapters that deal with problems related to improper interaction between the nervous system and the body. Here we learn about “the yips” that plague golfers and other occupational dystonias. When one begins practicing any physical activity, the objective is to build up muscle memory so that the movements can be completed purely unconsciously. This works through neuroplasticity—the fact that sequences of neurons that frequently fire together become more strongly linked—but neuroplasticity can have a dark side at the extremes.

Chapter 6 considers the way in which the system of maps can fail such that one fails to recognize one’s own limbs, one recognizes extra ones, or the like. Chapter 7 is about peripersonal space—i.e. the physical bubble of space that one needs to feel comfortable, and which varies both culturally and individually.

Chapter 8 delves into the role that upcoming technology may have in changing how we look at the body-brain connection. Mirror neurons are the subject of the penultimate chapter. You’ve probably heard of these neurons which fire when we see someone else perform an action. Usually there is an inhibitory signal to keep our body from actual mimicry, but sometimes you may find yourself unconsciously mimicking the position or body language of another person when one is engaged in an engrossing conversation. (Yawning contagiousness is a featured example.) Mirror neurons play a role in how we learn so quickly, how we sometimes anticipate the behavior or emotions of others, and deficient activity in these cells has been speculated to be responsible for autism.

Chapter 10 describes the role of the insula in human activities. The insula has been found to be involved in emotion and rewards system by which humans are motivated to engage in a number of bodily activities.

The book has many graphics to clarify technical points, many of these being line drawings of the brain and other physiological structures. There is also a glossary of key scientific terms.

I found this book to be fascinating. It was highly readable despite its technical subject matter, and it described these systems and the research about them in a clear manner. I’d highly recommend it—particularly if one is interested in movement, fitness, and optimal human performance.
