Today a brain scan reveals our thoughts and moods as clearly as an X-ray reveals our bones. We can actually observe a person's brain registering a joke or experiencing a painful memory. In Mapping the Mind, award-winning journalist Rita Carter draws on the latest imaging technology and science to chart how human behavior and personality reflect the biological mechanisms behind thought and emotion. This acclaimed book, a complete visual guide to the coconut-sized, wrinkled gray mass we carry around inside our heads, has now been completely revised and updated throughout. Among many other topics, Carter explores obsessions and addictions, the differences between men's and women's brains, and memory.
