A User's Guide to the Brain

from the back cover: "the brain is subject to the same kinds of influences and dysfunctions as other organs. Like a set of muscles, it responds to use and disuse by either growing and remaining vital or decaying, and thus, for the first time, we are learning to see mental weaknesses as physical systems in need of training and practice. The brain is a dynamic, highly sensitive yet robust system that may adapt, for better or worse, to almost any element of its environment. If we are going to set about training our brains to succeed in the world, we certainly need to learn about the various factors that can influence brain functions."
