The human brain is the most difficult organ in the human body to investigate. You can see a heart pumping, lungs filling, muscles moving, and stomachs churning to get some idea of how they work and what they do. However, just looking at a human brain in action doesn’t tell you about how it is functioning; no lights flash and no lobes pulsate. While CAT and MRI scans show you that things are happening, it is difficult to know what section of the brain is doing what. In fact, research has shown that often multiple locations of the brain are involved in even a single action or thought.
Because the brain is so difficult to study, over the years a lot of myths and misinformation about it have emerged. Doctors Sandra Aamodt and Sam Wang have written a book to try to not only explain what we know about the brain but, perhaps equally as important, identify many of the misconceptions we have about it.
This book goes into a fair amount of scientific detail but, by dividing it up into short sections, creating interesting “asides” sections, and presenting everything with as little jargon as possible the authors have geared this book toward the general public. They have also humanized it by including vignettes from their own lives to illustrate points they wish to make.
Neurology and the study of the brain is a rapidly changing field. This book was written in 2008 and several ideas mentioned are already becoming obsolete based on new discoveries utilizing more modern technology. Despite this, Aamodt and Wang have written a book that gives a lot of information that is both current theory and provoking of thought.
Daring to go into areas that many other authors skirt, Aamodt and Wang have sections about how brain function might relate to sex-linked test performance, drug use and abuse, sexual orientation, and religion. While I disagree with some of the ideas they present and a few of the theories mentioned have already been refuted by later study, I admire that they were willing delve into dangerous waters. Putting forth their ideas and the most current information available to them prods the reader into considering their own thoughts on these matters and to read further about areas that interest them.
The amount scientists know about the brain has increased dramatically over the past decade. However, the brain is not quick to give up its secrets and direct research is severely limited because it would be immoral to just jab probes or cut into a living brain. Fortunately, researchers are developing techniques to “peer inside” without using a scalpel. Let us hope that future discoveries will allow doctors to treat conditions that are currently untreatable.
Despite being a decade old, I enjoyed reading Welcome To Your Brain. I learned quite a bit, put into perspective some things I had learned in other books, and found that I held some old myths about brain function that have been repudiated.
