BOOK REVIEW: BrainComix by Jean-François Marmion

My rating: 5 of 5 stars Page

This nonfiction graphic novel surveys the brain and what it does, including: sensory processing, memory, attention, unconscious activities, learning, language, emotional experience, etc. It also reviews some of the more intriguing brain disorders (e.g. synesthesia, apraxias, phantom limb syndrome, etc.) and what they tell us about the nature of the mind.

If you’re looking for a soup-to-nuts overview of the brain that covers the gist without getting in too deep, and which is quick and easy, this book is hard to beat. If you have read much about neuroscience, you probably won’t be introduced to anything new. The book employs the usual suspects of pop-sci neuroscience and cognitive psychology: Phineas Gage (i.e. rebar through the brain guy,) H.M. (i.e. couldn’t form new memories after brain surgery guy,) the rubber hand experiment, the gorilla basketball experiment, etc. However, because it’s such a quick and light read, it’s not much of an investment to review these topics, and – who knows – maybe you’ll retain more due to the graphics.

The premise is a simple one, the brain is being interviewed for a Larry King-style talk show that at times becomes a Jerry Springer-style show as “characters” (e.g. a neuron, a homunculus, the conscious mind, etc.) charge the stage to get in their two cents. This might not be the most creative or clever approach that could’ve been taken, but it also doesn’t distract from the objective of teaching about the brain – as a more intense plot might have done. The art is crudely drawn, though I suspect this is on purpose to make clear this is not a textbook, but rather a pop-sci book.

If you are looking for an introduction to the brain, you should check this book out. (Also, if you’re looking to review, quickly and concisely, you might find it of value as well.)

BOOK REVIEW: Proust & the Squid by Maryanne Wolf

Proust and the Squid: The Story and Science of the Reading BrainProust and the Squid: The Story and Science of the Reading Brain by Maryanne Wolf
My rating: 5 of 5 stars Page

Time to get meta, and do some reading about reading. Wolf’s book explores the neuroscience of reading, the evolution of writing systems, and what keeps some children from learning to read as rapidly as most. If you’re wonder about the seemingly arcane title, Proust’s essay “On Reading” planted a seed of thought that would become this book. The squid bit reflects the aquatic creature’s famous neurological adaptability, which is also witnessed in the learning human brain. Reading as both a mystic experience and as the unanticipated consequence of an extremely plastic brain are among the book’s recurring themes.

Another recurring idea is that reading has a cost. This view was famously expressed by Socrates, who believed reading would contribute to diminished memory, intellectual laziness, and other problems. Wolf reflects upon Socrates’ criticisms, but also draws a parallel between Socrates’ ideas on the subject and the present-day argument that the internet / social media is driving us inexorably and inevitably toward an “Idiocracy” type world.

The parts of the book that deal with the neuroscience of reading do get a bit complicated. It would be hard for them not to as reading is a complex task unfolding within the most complex system that we know of. However, wouldn’t say that this book is any more dense or incomprehensible than most pop neuroscience books – especially as it’s mixed in with less challenging material.

My understanding of dyslexia (Ch. 7 & 8) grew considerably while reading this book. I learned that it isn’t a unitary affliction, but can come about at any of a number of cognitive tasks that have to transpire during reading.

If you’re interested in how humanity learned to read, the benefits and costs of this capacity, and what dyslexia really is, this book is definitely worth reading.

BOOK REVIEW: Hurts So Good by Leigh Cowart

Hurts So Good: The Science and Culture of Pain on PurposeHurts So Good: The Science and Culture of Pain on Purpose by Leigh Cowart
My rating: 5 of 5 stars Page

Out: September 14, 2021

Humans devote a lot of effort to avoiding unpleasant sensations. I’ve even heard people philosophize that all human activity is about moving toward pleasure or away from pain, but this claim fails on two grounds. First, people don’t invariably flee from pain, sometimes they run into its arms. Second, the dichotomization of pleasure and pain, categorizing them as opposites, also fails for a wide variety of human endeavors.

This book reflects upon a diverse set of cases in which the pleasure-pain dichotomy breaks down, attempting to glimpse why this is the case. Cowart investigates pepper-eating contests, ultramarathons, Polar Bear Club mid-winter dips, flagellation by religious adherents, and sexual sadomasochism. One thing these diverse activities have in common is that individuals voluntarily and purposefully subject themselves to intensely painful sensations. Throughout the book, the author is forthright about the varied ways that she has been attracted to pain, including: ballet dancing, an eating disorder, and sexual masochism.

This book takes a story-centric approach. As the subtitle suggests, it does present scientific findings, but this information is tucked in amid the stories – both her own confessional tales and the stories of the masochists (broadly speaking, i.e. not referring only to sexual pain-seekers) she meets during her research trips.

As a student of both martial arts and yoga, I found that the changing of one’s perception of, and relationship to, sensation is one of the most profound and empowering aspects of these practices. I, therefore, was curious what brought people to the purposeful pursuit of pain and what benefits others found. Not surprisingly, there isn’t just one reason for all cases, and Cowart discusses neurochemical, social, and psychological reasons. If you’re curious about why people engage in pain purposefully and voluntarily, this book is a must-read.

BOOK REVIEW: Cognitive Neuroscience: A Very Short Introduction by Richard Passingham

Cognitive Neuroscience: A Very Short IntroductionCognitive Neuroscience: A Very Short Introduction by Richard Passingham
My rating: 4 of 5 stars Page

This book provides a brief overview of cognitive neuroscience, a discipline that has really only been around for the past few decades, one that uses technologies allowing scientists to see what parts of the brain are active during a given mental activity. The reader learns what parts of the brain are involved in the various activities of being human from perception through action, and what can go wrong with these processes. While that sounds simple and straightforward, the immense complexity of the brain makes it anything but, and there is a lot of medical jargon and qualifying statements to explain how a given relationship between brain location and activity isn’t as simple or well understood as we are frequently led to believe. [Any plain and direct explanation of the brain workings is likely to be at best partial truth, and more likely outright deceptive.]

I found the organization of this book to be logical and conducive to learning about this complex and technical topic. The first chapter, “A Recent Field,” describes what cognitive neuroscience is and where it fits in among the various sciences that deal with mental activity including, psychology, psychiatry, etc. This gives one an idea of both how cognitive neuroscience can contribute to our understanding of mental activity, but also where its limitations lie and why it has not displaced all the other disciplines.

Chapters two through eight make up the core of the book and present an exploration of the various aspects of mental activity and what has been learned about them through studies in this field. The progression is logical and elementary: perception (Ch. 2,) attention (Ch. 3,) memory (Ch. 4,) reasoning (Ch. 5,) decision (Ch. 6,) confirmation / checking (Ch. 7,) and finally action (Ch. 8.) In each chapter practical questions are discussed, questions that will be of interest to readers whose goal is not vocabular expansion, in addition to the discussion of what brain region is involved with what activity. What kinds of questions? How amputees “feel” pain from the missing part of the body? Why humans suck at multitasking, and under what circumstances they can do better at it? How come people who have amnesia remember how to talk and engage in physical activities? Is there free will, and – if so – in what sense? Do we think in language? Etc.

The last chapter reflects upon the future of the discipline. Over the course of the book, the reader learns the limitations of what functional Magnetic Resonance Imaging (fMRI) and Positron Emission Tomography (PET) scans can tell one about what is happening with the brain, and in this chapter one is introduced to the next generation of technologies that may take our level of understanding to another level.

This book has an excellent feature that I don’t recall seeing in other AVSI books. (That is probably, in part, because many of them don’t need it like this one because their subject matter is more readily grasped.) Said feature is a text box at the beginning of the chapter that asks some relatively rudimentary and practical questions, and then – at the end of the chapter – those questions are answered in another box. I think the author recognized that there was a high degree of risk of losing readers if the entire book was, “and when you do decide how many minutes to microwave your Hot Pocket, the temporo-parietal junction works in conjunction with the …” [not an actual quote fragment] he would produce book of limited benefit. [i.e. it would be too technical for the neophyte reader who just wants some practical insight (the AVSI target demographic,) but not technical enough for students of brain anatomy.] These text boxes help keep the reader focused on what is being conveyed while not getting too caught up in arcane terminology.

Other ancillary matter includes graphics (photographs of technology and readouts and diagrams showing where brain areas are located,) references, and a further reading section.

I found this book to have some intriguing discussions on interesting topics. That said, those discussions are interlaced with some necessarily complicated and dense subject matter (that’s the nature of the discipline.) That said, I think the author recognized his challenge and the question boxes and answer boxes that bookended the core chapters were very useful in offering focus for a non-expert reader. It you want a bare-bones overview of cognitive neuroscience, it’s worth reading this slim volume.

BOOK REVIEW: The Art of Impossible by Steven Kotler

The Art of Impossible: A Peak Performance PrimerThe Art of Impossible: A Peak Performance Primer by Steven Kotler
My rating: 5 of 5 stars page

Out: January 19, 2021


Steven Kotler’s new book, “The Art of Impossible,” shares territory with two of his previous books [“The Rise of Superman” and “Stealing Fire” (the latter co-authored with Jamie Wheal,)] but it also takes a step back to reveal a broader landscape than those previous books. Whereas the earlier books focused on how to achieve a high-performance state of mind called “flow” (or “peak performance,”) this one looks at the bigger picture of how to achieve success with daunting projects. So, while the fourth / final section of the book presents information that will be familiar to past readers, the first three sections – on motivation, learning, and creativity, respectively – are not addressed in the earlier works. [It’s worth pointing out that even section four (Ch. 19 – 23) presents some new information and organizational schemes because this is a fast-moving research domain of late.]

The book’s first six chapters (i.e. Part I) are about achieving and maintaining motivation. This starts from the logical bedrock of finding an “impossible” task for which one is likely to have sufficient passion and interest to follow through. The reader learns how to formulate goals that are challenging enough and clear enough to facilitate sustained interest, effort, and productivity. The importance of autonomy is discussed at length, and the reader learns what companies like Google, 3M, and Patagonia have done to make gains via employees energized by increased autonomy. The kind of motivation that allows one to knuckle-down under adversity, grit, is given its own chapter, and the author discusses six variations that are important to success.

Part II (Ch. 7 – 14) is about the learning process and how one can organize one’s pursuits to get the most learning per effort. Chapter ten is the heart of this section, offering a detailed approach to organizing one’s learning activities. Chapter fourteen offers yet another critique of the 10,000-hour rule that was popularized by (and oversimplified in) the Malcolm Gladwell book, “Outliers.” [This “rule,” developed by Swedish psychologist Anders Ericsson, has come under intense criticism in large part because every time the explanation shifted downstream it became less of an approximate rule of thumb that was applicable to some specific domains and more of an iron-clad rule deemed applicable to every activity that benefits from practice, resulting in insane behavior such as parents who pick their child’s sport in the womb so that the kid can get the requisite number of practice hours before the college recruiters come to see him or her play.]

The third part (Ch. 15 – 18) is about fostering creativity. Here, Kotler takes the reader on a tour of changing thought about creativity, ranging from the ancient stories of muses to today’s state-of-the-art neuroscience. Like the section on Flow, there is an elaboration of where the neuroscientific understanding of creativity sits at the moment. Having read a range of books discussing such descriptions, this approach is falling out of favor with me. First, whenever I’ve read a book by an actual neuroscientist, I’ve learned that these simple attributions of activities to certain brain regions are either vastly oversimplified, more tentatively agreed upon than suggested, or both of the above. Second, I have realized that learning a name like Anterior Cingulate Cortex (ACC) and an oversimplified explanation of what it does doesn’t really help me. That said, I understand there is interest in these descriptions that drive their inclusion in such books. (I, too, have been interested in reading about it, but less and less so.)

The final part is about Flow, and this is where readers of “Rise of Superman” will be well-primed for the information that is covered. Chapter 21, which elucidates the twenty-two “Flow Triggers,” is the heart of this section. As I mentioned, Kotler has changed the way he organizes this discussion since his earlier book, but the material is still largely from Mihaly Csikszentmihalyi’s work on the subject. In addition to explanation of what it means to get into the state of Flow and of how to improve one’s chances of getting there, there is a discussion of “Flow Blockers” – four mind states that hinder Flow. The last chapter lays out a plan consisting of daily and weekly activities, and – as such – it serves as both a summary and an outline for moving forward.

Writers may find this book particularly beneficial because Kotler relies heavily on anecdotes from his own work to clarify and explain the points under discussion. By contrast, “Rise of Superman” relied almost exclusively on stories from extreme sports athletes, and “Stealing Fire” drew on silicone valley and the special forces heavily for examples. I actually enjoyed that Kotler spoke from his own experience. As someone who has read a fair number of books on peak performance, I’ve seen a lot of the same stories repeated within popular books. That said, readers who haven’t read much on the topic may wish the book had a broader set of narrative examples and less definitional / conceptual discussion. The author may be aware that many of his readers will have fatigue from reading the same stories and examples. When Kotler does mention such widely-discussed examples (e.g. Steve Jobs putting bathrooms in the Pixar building in a central location that created cross-pollination of people on different projects) he does so briefly and without preaching to the choir.

I found this book to be an interesting overview of how to approach a large-scale life mission. It’s well-organized and readable (though it might benefit from less vocabulary-based neuroscience discussion.) If you are feeling a bit rudderless, this is a good book to look into.

BOOK REVIEW: The Science of Storytelling by Will Storr

The Science of StorytellingThe Science of Storytelling by Will Storr
My rating: 5 of 5 stars

Amazon page


Many books have been published on the science of story since the realization that storytelling is as fundamental to humanity as tool-making and bipedalism. The first such book that I reviewed was Lisa Cron’s 2012 “Wired for Story.” So, the question of interest isn’t whether the topic is fascinating (it is) but – instead – whether Storr’s book offers value-added. I believe it does. While Cron and Storr cover some of the same territory, the differences in approach lead to variations in the material covered and the emphasis given. Storr orders his book around his particular method of story building, which he refers to as “the sacred flaw approach.” He proposes that at the heart of a story is an erroneous assumption to which the lead character wishes to cling. This is where he tries to stake his claim among the vast number of books offering advice on story – i.e. by focusing on character flaw, rather than on the sequence of events (i.e. plotting.)

The appeal of this topic will vary according to who’s asking, but for writers there’s certainly a desire to unravel the mystery of story. Every story builder would like to venture into new and uncharted territory, but there seem to be key criteria around which stories live or die. The most glaring illumination of this can be seen when filmmakers spend tens or hundreds of millions on films that utterly flop, and when they spend that much money and flop it’s not because the CGI was hinky. It’s inevitably because the story lacked appeal. At its worst, this has led to strategies such only rebooting films that have worked in the past, and at it’s best it results in following one of the many fixed patterns (e.g. Joseph Campbell’s “the hero’s journey.”) Understanding the science of story offers the hope of being able give one’s audience what they need to find a story fulfilling without following a beat-by-beat sequencing from a manual — in the manner of a pre-flight checklist.

The book is divided into four chapters that are designed to look at story through its various levels, and within each chapter there are many subsections. The chapters are: 1.) creating a world; 2.) the flawed self; 3.) the dramatic question; and 4.) plots, endings, and meaning. Chapter 1 isn’t just advice about how to build the story environment, but rather it looks at how our brains take in and model the world as written so that one can use that knowledge to more smartly approach presenting a world. As one might guess, chapter two is a crucial one because it introduces the study of characters and their flaws, and why said flaws are critical to the appeal of a story. The author also addressed differences between Eastern and Western approaches to story and I found the discussion of culture to be an intriguing inclusion. Chapter three continues the work of the second by focusing on how the interaction of subconscious and conscious minds contribute to a protagonist’s problems. In keeping with the coverage of culture, there’s a section that looks at stories as tribal propaganda that was quite insightful. The final chapter examines how plots and good endings arise as a logical result from setting up the character.

There’s an appendix that lays out Storr’s “Sacred Flaw Approach.” This is the approach that he teaches in his writing course. The book is also annotated, though it is text-centric and doesn’t employ much in the way of graphics.

I found this book fascinating. It does rehash some of the same examples as other books on story (e.g. “The Godfather” movie,) that’s simply because those stories are widely known and thus have broad usefulness. But there were plenty of insights to keep me intrigued, even having read other books on the topic. If you’re interested in the science of storytelling, this book is worth giving a look.

BOOK REVIEW: The Science of Meditation [also sold as Altered Traits] by Daniel Goleman and Richard Davidson

The Science of Meditation: How to Change Your Brain, Mind and BodyThe Science of Meditation: How to Change Your Brain, Mind and Body by Daniel Goleman
My rating: 5 of 5 stars

Amazon page


This book has been sold under the title listed above as well as the less prosaic title, “Altered Traits.” The switch may represent a lack of confidence that the coined term “altered traits” would catch on, and / or a desire to market the book as broadly as possible.

“Altered Traits” is a play on the more well-known term “altered states [of consciousness.]” The idea being that meditation (as well as many other activities from consuming psychoactive drugs to having a shamanistic drum rave) create a change from the ordinary waking state of consciousness, but what the authors wanted to focus more upon is the long-term and sustained changes that result from extended meditation practice. (Hence, coining the term “altered traits.”) These sustained changes are a prevalent theme through out the book. This makes sense as one of the co-authors, Richard Davidson, is well-known for investigating the brains and brain activity of monks and yogis with extremely advanced practices (tens of thousands of hours in meditation.) Still, the prosaic title, “The Science of Meditation,” may make more than marketing sense because the book does discuss the scientific research on meditation pretty broadly.

Both Goleman and Davidson are long time meditators as well as being subject matter experts in psychology and brain science. This is a major strength of the book. Some scientists are dismissive of practices that have origins in spiritual practices and have blindsides or are prone to oversimplifications because of that bias. On the other hand, that bias isn’t helped by the fact that meditation experts often oversell meditation as a practice that will do everything from spontaneously cure your cancer to allow you to levitate six feet in the air. The authors of this book aren’t afraid to call out such spurious claims, but aren’t dismissive of practices of religious or spiritual origin. The authors also spend a fair amount of time criticizing past scientific investigations of meditation (including their own) on the basis of naivete about the nature of the practices. A major problem has always been an “apples and oranges” grouping together of practices that are different in potentially important ways. There have also been all the problems that plague other disciplines as well (small sample size, poor methodology, etc.) These discussions won’t mean much to most readers, but are helpful to those who want a better idea which studies are gold standard and which are weak. That said, the book doesn’t get bogged down in technical issues.

The book opens by laying out some of the important differences between various meditation practices and trying to educate readers who may either not know much about meditation or may know it only from the perspective of a single discipline. Goleman and Davidson suggest one way of thinking about different kinds of meditation is in terms of “the deep and the wide.” The former being sectarian practitioners who practice specific ritualized practices in an intense way. The latter being more secular practitioners whose practices may borrow from different domains. They present a more extensive classification scheme than this simple bifurcation, making it more of a continuum. Later in the book, they consider ways in which practices might be categorized (e.g. Attentional, Constructive, and Deconstructive) but it’s emphasized that there isn’t currently an agreed upon schema.

Throughout the book, one gets stories of the authors experience in investigating this subject. This included trying to get monks to allow themselves to be studied, even with a letter from the Dalai Lama. It also covers the challenge of trying to build interest in the subject in an academic setting that once thought of meditation as little more than voodoo.

The middle portion of the book has a number of chapters that address particular types of practices and the specific effects they have (and haven’t) been found to have. These include developing a more compassionate outlook and behavior (ch. 6), improved attention (ch. 7), negation of pain and physical ailments (ch. 8 & 9), and meditation / mindfulness as part of a psychotherapeutic approach. The authors repeatedly point out that these practices were never intended for the purpose of treating ailments (mental or physical,) though they do seem to show benefits in a number of domains outside of what the spiritual seekers who brought them to prominence intended of them.

The chapters toward the book’s end focus heavily on investigations into advanced meditators, and the altered traits and brain changes seen in them.

There are few graphics in the book, but it’s annotated and has an “additional resources” section in the back.

I’d highly recommend this book. The authors’ mixed background gives them a good vantage point to provide an overview of the subject, and also allows them to tap into stories of their experiences which make the book more interesting than it otherwise would be.

BOOK REVIEW: Why We Sleep by Matthew Walker

Why We Sleep: The New Science of Sleep and DreamsWhy We Sleep: The New Science of Sleep and Dreams by Matthew Walker
My rating: 4 of 5 stars

Amazon page


For a long time, the questions of why we sleep and dream remained unanswered — or answered speculatively in ways that proved without merit. One presumes the reasons are potent because there seems to be little evolutionary advantage in spending a third of one’s life unconscious of one’s environs and paralyzed (literally in REM sleep, but for all intents and purposes in NREM sleep as one can’t respond to changes in the environment without some part of one’s brain taking note of said changes.) The good news is that Matthew Walker’s book offers insight into what scientists have learned about why we sleep, why we dream, why we become so dysfunctional without doing both, and what it is about modern life and its technologies that has created an apparent crisis of sleep loss. Walker goes beyond the science to discuss what individuals and institutions can do to reduce the harmful effects of sleep deprivation.

The downside of this book is that it’s a bit alarmist, and in contrast to many books of this nature one doesn’t get a good indication of the quality of studies reported. Some pretty brazen claims are made and the reader doesn’t necessarily know if they are preliminary and unvalidated or if they are well established. Here, I’m speaking about the studies that try to isolate out the effect of sleep loss versus all other factors (which is a notoriously messy affair,) and not so much studies that report on the physiological effects of sleep and sleep loss (which I see less reason to not take at face value.) At any rate, any reader who doesn’t fall asleep as soon as his head hits the pillow and sleep straight through 7 hours and fifty-five minutes — waking 5 minutes before the alarm — is likely to feel doomed if they take this book too seriously. And if you ever engaged in shift-work (as I have) or had an intense travel schedule, you are likely to feel that your life is permanently and irretrievably wrecked.

I know this is a book on sleep, but I think it went a little too far in marginalizing all other elements of health and well-being. Walker said that he used to tell people that sleep, nutrition, and exercise were the trifecta of good health, but he ultimately concluded that sleep was more important because diet and exercise were adversely impacted by sleep loss. I don’t disagree that diet and exercise are harmed by sleep loss, but – of course – sleep quality is harmed by lack of proper diet and exercise as well. The author later discusses research confirming this two-way street. I, therefore, have no idea why he changed his initial balanced and reasonable view with one that suggests sleep is the 800-pound gorilla of health and well-being.

The book’s 16 chapters are divided into four parts. Part I (Ch. 1 – 5) lays out what sleep is, how rhythms of sleep are established / disrupted, how much sleep one needs, and how one’s sleep needs change throughout the course of one’s life. Part II (Ch. 6 – 8) explores the benefits of sleeping as well as describing the nature of the damage caused by lack of sufficient sleep. Part III (Ch. 9 – 11) shifts the focus to dreams, and delves into what they appear to do for us. The final part (Ch. 12 – 16) investigates the many ways in which modern life disrupts sleep from blue light in LED’s to arbitrary school and work schedules to cures that are worse than the ill (i.e. sleeping pills.)

There is an appendix that summarizes twelve key changes that an individual can make to get more and better sleep. There are graphics throughout the book, mostly line-drawn graphs to provide visual clarity of the ideas under discussion.

I found this book interesting and informative. I would recommend it for anyone interested in the science of sleep or how they might sleep better, with the exception of anyone who has anxiety about the state of his or her health and well-being. While I understand that Dr. Walker wants to drive changes regarding views and policies that have been wrong-headed or deleterious regarding sleep, I feel he went too far toward suggesting the sky is falling for anyone who gets less than a perfect night’s sleep every night of his life.

BOOK REVIEW: Anxious Joseph E. LeDoux

Anxious: Using the Brain to Understand and Treat Fear and AnxietyAnxious: Using the Brain to Understand and Treat Fear and Anxiety by Joseph E. LeDoux
My rating: 5 of 5 stars

Amazon page


This book examines the neuroscience of anxiety, though psychology also makes a prominent appearance in the discussion – particularly toward the end of the book. It’s written by one of the top researchers in the field emotional neuroscience, though LeDoux discusses the work of other labs, comparing and contrasting their work with that of his own, and thus giving an idea of the fault lines in the field. (By that I mean more the questions that remain in dispute, not who hates whom.)

The book addresses a number of key questions such as: How does brain activity result in the emotional experience? How do conscious emotional feelings relate to and interact with non-conscious responses to threatening stimuli? Is the human emotional experience a hand over from animal ancestors or a uniquely human condition? How effective are drug-based versus psycho-therapeutic approaches to anxiety disorders? What has been learned about extinguishing anxious responses to threatening stimuli? Needless to say, this book doesn’t answer all the questions, as many of the questions – particularly those regarding consciousness – remain to be definitively answered. It does offer a great overview of the state of understanding in the present day.

I won’t present a chapter by chapter outline, but rather a look at the book’s general flow. LeDoux starts by laying groundwork, and in this case that means clarifying the relationship between fear and anxiety. While the former often captures the imagination because of its dramatic and traumatic causes, the latter is more of a concern as its grinding long-term effects can cripple the immune system and have other adverse effects. The early chapters also discuss what has been learned about how emotions are formed in the brain and how views about this have changed over time.

Chapter five is where LeDoux explores the relationship between animal emotionality and human emotional life. This is an important subject as it relates to the question of whether research with animals can teach us anything relevant to the human experience. As it has become progressively more difficult to conduct any research that causes human subjects any emotional distress, this question may be instrumental to making progress in the field.

Chapters six through eight are interconnected by the question of consciousness. Chapter six discusses the nature of consciousness, which remains one of the most slippery and least understood concepts in the natural world. Chapter seven delves into memory and consciousness – an important topic as anxious responses can be viewed as learned responses and this begs the question of unlearning. Memory will later be revisited with respect to the question of whether it’s possible to erase painful or anxiety-inducing memories (ala, “Eternal Sunshine of the Spotless Mind”) – based on work that came out of LeDoux’s lab – and, if so, whether it’s a good idea. The final consciousness chapter gets into consciousness of emotion, specifically (as opposed to all the other thoughts and feelings of which one can be consciously aware.)

The last three chapters are also interconnected by movement from the question of how is anxiety felt / experienced to the question of what one can do about it. The first of these chapters discusses an epidemic of anxiety (entitled “40 million anxious minds,” and that refers to the US alone) and what has been learned about drug-based treatments. As it happens, drug-based treatments haven’t proven reliably effective, leaving plenty of room for other approaches, e.g. psychotherapy. This fact is the basis for the last two chapters that discuss different approaches to extinguishing the connection between a stimulus and the anxious response. The first of theses chapters (ch.10) is more general and the last chapter dives deep into the research that has been done in recent years. Chapter 11 also offers a nice discussion of how breath exercises and meditation can be instrumental in reducing the adverse effects of anxiety.

As would be expected of a scholarly work, the book is heavily annotated, has an extensive bibliography, and uses a great number of graphics in an attempt to lend clarity.

I would put this work in the same category as the works of Robert Sapolsky. That is to say, it resides in a space between the level of detail usually seen in works of popular science and that which is seen in textbooks for specialists. That is to say, LeDoux does get into some detail and this isn’t a light read for anyone without a heavy-duty background in biological sciences. That said, if you have a basic scientific literacy (and / or don’t care too much about the fine detail), it’s by no means impossibly dense. When it’s not diving into the various brain regions and neuronal pathways, it’s quite readable.

I’d recommend this book for anyone who is interested in a detailed look at how anxiety arises and how it can be quelled.

BOOK REVIEW: Behave by Robert Sapolsky

Behave: The Biology of Humans at Our Best and WorstBehave: The Biology of Humans at Our Best and Worst by Robert M. Sapolsky
My rating: 4 of 5 stars

Amazon page


This book examines the role of biology in the best and worst of human behaviors – as well as presenting factors that compete with or complement biological explanations, as the author finds relevant. Sapolsky is neuroscientist (specifically, a neuroendocrinologist) with a unique perspective as his research cuts across species – involving not only human beings but also baboons. Sapolsky investigates why humans fight, cooperate, rape and forgive by comparing and contrasting human behavior with what is seen in the animal kingdom.

The first thing a potential reader must realize is that Sapolsky dives into the weeds more so than most scientists writing for a popular audience. This will be a plus if one’s grasp of science (biology, in particular) is strong. However, if the reader hasn’t read anything on biology since high school or freshman year of college, one is likely to find the names and descriptions of hormones and neurochemicals, brain sectors, and protein processes a bit daunting. The book has three appendices that offer primers on neuroscience, endocrinology, and proteins, respectively, to get readers up to speed on the basic science. Furthermore, Sapolsky is quick to point out what can be skipped by readers who don’t want so much detail. I don’t want to give the impression the book is boring. Sapolsky uses humor and story to good effect. It’s just that he gets into Latin names and physiological minutiae at a level that most of his counterparts don’t, and that some readers will find challenging.

While not formally divided so, the seventeen chapters of the book can readily be split in two parts. The first ten chapters discuss the types of behavior that Sapolsky is taking on, and then work back from what happens immediately before a behavior (i.e. one second before) through neuronal, hormonal, and other proximal causes to the far distant causes rooted in human evolution. The first half of these chapters take one to a point in the individual’s life at most months out from the behavior under consideration. Chapters six through eight go back to the individual’s youth, exploring the role of adolescence, infancy, and fetal development. Chapters nine and ten peer back before the birth of the individual to those who contributed indirectly to the individual’s vice or virtue, including the role of the broad run of human evolution. It should be pointed out that this first part is where the aforementioned technical depth is mostly observed.

The second part of the book changes the approach by taking a more topical approach. Said topics include: us/them discrimination, hierarchy (and the acceptance / rejection thereof), morality, empathy, metaphors and symbols that become integral to good and bad behavior, the biology of free will (or the lack thereof,) and consideration of the question of whether humanity is getting more peaceful (as Steven Pinker argues in his book “The Better Angels of Our Nature” [which is arguably one of the main competitors to Sapolsky’s book, though the focus is a little different.]) This second part gets much more into the social science perspective, and isn’t as scientifically dense as the first portion of the book.

I would recommend this book to anyone interested in the good, the bad, and the ugly of human behavior. With the exception of getting a little technical in spots, it’s quite readable and interestingly organized and presented. As one can’t help get into political and cultural norms in a book on human behavior, Sapolsky betrays his personal biases here and there, but is quick to admit when there is evidence against them (or no evidence at all, either way.) I felt he maintained a reasonable scientific objectiveness, but others may feel differently.
