Mapping the Mind charts the way human behavior and culture have been molded by the landscape of the brain. Carter shows how our personalities reflect the biological mechanisms underlying thought and emotion and how behavioral eccentricities may be traced to abnormalities in an individual brain. Obsessions and compulsions seem to be caused by a stuck neural switch in a region that monitors the environment for danger. Addictions stem from dysfunction in the brain's reward system. Even the sense of religious experience has been linked to activity in a certain brain region. The differences between men and women's brains, the question of a "gay brain," and conditions such as dyslexia, autism, and mania are also explored.
Looking inside the brain, writes Carter, we see that actions follow from our perceptions, which are due to brain activity dictated by a neuronal structure formed from the interplay between our genes and the environment. Without sidestepping the question of free will, Carter suggests that future generations will use our increasing knowledge of the brain to "enhance those mental qualities that give sweetness and meaning to our lives, and to eradicate those that are destructive."
Carter and her scientific editor, neuropsychologist Christopher Frith, cover the state of the mind in a reasonably accurate, accessible way. They emphasize topics that are likely to be of some practical interest--such as Alzheimer's or attention deficit disorder--but not so much as to give a distorted picture of the field.
Perhaps the most interesting parts of the book are the sidebars written by a variety of leading names in mind-brain science. Roger Penrose writes on computer minds, Francis Crick on consciousness, Steven Rose on memory, John Maynard Smith on social evolution, William Calvin on mosaic minds, Kay Redfield Jamison on creativity and bipolar disorders, and more. It's a stellar assortment, more than worth the price of admission--and there's a map of the mind on the cover, in case you misplace yours. --Mary Ellen Curtin
