The Body Has a Mind of Its Own: How Body Maps in Your Brain Help You Do (Almost) Everything Better ReviewThis is an excellent book. The authors have a gift for making a complex subject understandable. Another plus is that, like the best of nonfiction authors, they stick to the subject and rely on facts rather than opinion. This book provides a wonderful introduction into an area of science formerly limited to neurologists and other highly-trained specialists.
Central theme
The central theme of this book is that the brain maps the body. In fact, different areas of the brain contain different kinds of body maps with different functions. These body maps in the brain determine such things as how you perceive reality and how you respond to that perception. One of the most fascinating aspects is the plasticity of these maps.
For example, have you ever noticed that you can "feel" with the end of a tool? You put a wrench on a nut, and you suddenly have several important bits of information about that nut. This is because your body map extends to include the tool. And it's why mechanics can accurately work without actually seeing what their hands or tools are touching. Body maps extend from the rider to include the horse and from the horse to include the rider. Lovers share body maps, and the book explores what goes on there also.
This book explores the effects of dysfunctional body maps, too, shedding light on such things as eating disorders and out of body experiences. And it looks at the interplay between body maps and culture, language, music, emotions, pain, and even parenting.
The brain and the body are not separate entities, but are intertwined, interdependent, and interfunctional. Understanding this fact is essential to understanding how and why body maps work. This book explains that lucidly.
You may have heard of the "little man" theory, or the homunculus theory. If not, perhaps you recall the drawing of the skull being opened to reveal a little man operating control levers. That drawing represents the theory. We all know there's not an actual physical person of tiny stature pulling levers in our heads. But it's commonly thought that the "me" of us is a central entity that works like that little man. Another common analogy for this theory is the symphony conductor.
Because of this theory, many early researchers of body maps looked for the master map. As it turns out, there isn't one. There is not "little man," no master homunculus, no conductor, no central authority. The brain is a collection of homunculi or body maps working together. If this doesn't sound possible, think of an ant colony. There is no master ant giving out directions. Each ant does its part in a concert of ants with no conductor. The many body maps of the brain are similarly independent yet cooperative. The brain also contains body maps that facilitate the communication between these disparate parts and the various body maps those parts use.
Only flaw
The book runs a couple hundred pages, in an unusually small typeface. It would be better, in a future release, to be produced in a larger font. I don't think anyone over about the age of 30 can read it unaided. This production issue is the one flaw in this book, and I hope the publisher decides to spend a bit more on paper to fix that in the next printing.
Summary of contents
The Body Has a Mind of Its Own consists of 10 chapters. The first chapter gives the reader the background about body maps and how they are everywhere in the brain. Chapter Two talks about the little man theory discussed earlier in this review.
Chapter Three talks about how body maps filter and change incoming information to conform to what the map expects to see. You've no doubt heard the expression "People hear what they want to hear." That is a basic aspect of our brain, which is a prediction machine. It's always looking for matches. Just as politicians change the data to match their statements, so quite often does the brain change or filter information so that it matches what the brain expects to see. This is the basis for illusions, and we all know those work.
Sometimes these illusions don't serve us very well. One example the book uses is the anorexic who feels fat. This prediction thing isn't all bad--many self-help experts advise us to imagine ourselves as having already achieved something or to take on some other enabling attitude.
Chapter Four takes the concepts of Chapter Three a step further, and looks at why mental practice--long used by martial artists--is nearly as effective as physical practice and why when both are done you get a 2 + 2 = 5 effect.
Chapters Five and Six explore what happens when body maps blur or break. Some of the manifestations are bizarre.
Earlier, I mentioned that when you grasp a tool your body map extends to include that tool. Chapter Eight includes a discussion of this in the broader context of where body maps end. Chapter Seven also talks about where body maps end, but more in terms of how they seek to exclude things that are not part of the body.
Sales trainers talk about mimicking other people to win their agreement. In Chapter Nine, we see why this works.
Deep in the brain is a structure called the insula. Only mammals even have one. In humans, it's massive compared to those of other species (relatively speaking--in whales, body parts are just plain bigger on an absolute scale). The consensus now is the insula is the seat of emotional awareness. Chapter Ten, in discussing the insula, is a fitting last chapter because it is, at least to me, the most profound part of the book.
The authors tie everything together in the Afterword, but also raise additional questions that are worth pondering as we search for meaning and purpose in life.
Descartes concluded that because he thinks he must exist. Has your human mind has ever contemplated itself, trying to answer the question, "Who am I? Or have you wondered about where in your body your mind actually resides? The Body Has a Mind of Its Own will help you bring some fascinating information to bear on those concepts and many others. Not only is this book thought-provoking, but it helps explain thought itself. How you perceive reality may not be as straightforward as you once thought. Or still think, depending on your body maps.The Body Has a Mind of Its Own: How Body Maps in Your Brain Help You Do (Almost) Everything Better Overview

Infinite Reality: Avatars, Eternal Life, New Worlds, and the Dawn of the Virtual Revolution ReviewThis is the kind of book that blows your mind on a regular basis. The studies that Bailenson and Blascovich design and report on are difficult to stop thinking about. These authors look at technology as a way to understand who we are and who we will become, answering key philosophical and psychological questions along the way.
They have described their approach as Transformative Social Interaction, and if anything, this is an understatement. These researchers use the virtual world as a testbed to examine psychological issues in ways that simply were not possible before. And rather than this being reported to you through the lens of a journalist, this comes straight from the pioneers in the field.
And while its easy to imagine this kind of heady stuff being dense and difficult to read, or full of techie jargon, your imagination would be wrong. The book is a delight to read, with humor and insight and intellectual curiosity mixed in equal doses.
I highly recommend this book to anyone interested in the human condition, in how technology is transforming our future, or in reading some of the most cutting-edge, fascinating psychology out there.Infinite Reality: Avatars, Eternal Life, New Worlds, and the Dawn of the Virtual Revolution Overview
How do The Matrix, Avatar, and Tron reveal the future of existence? can our brains recognize where "reality" ends and "virtual" begins? What would it mean to live eternally in a digital universe? Where will technology lead us in five, fifty, and five hundred years?

Two innovative scientists explore the mystery and reality of the virtual and examine the profound potential of emerging digital technologies

Welcome to the future . . .

The coming explosion of immersive digital technology, combined with recent progress in unlocking how the mind works, will soon revolutionize our lives in ways only science fiction has imagined. In Infinite Reality, Jeremy Bailenson (Stanford University) and Jim Blascovich (University of California, Santa Barbara)-two of virtual reality's pioneering authorities whose pathbreaking research has mapped how our brain behaves in digital worlds-take us on a mind-bending journey through the virtual universe.

Infinite Reality explores what emerging computer technologies and their radical applications will mean for the future of human life and society. Along the way, Bailenson and Blascovich examine the timeless philosophical questions of the self and "reality" that arise through the digital experience; explain how virtual reality's latest and future forms-including immersive video games and social-networking sites-will soon be seamlessly integrated into our lives; show the many surprising practical applications of virtual reality, from education and medicine to sex and warfare; and probe further-off possibilities like "total personality downloads" that would allow your great-great-grandchildren to have a conversation with "you" a century or more after your death.

Equally fascinating, farsighted, and profound, Infinite Reality is an essential guide to our virtual future, where the experience of being human will be deeply transformed.
