In A User's Guide to the Brain, Dr. John Ratey, best-selling co-author of Driven to Distraction, explains in lucid detail and with perfect clarity the basic structure and chemistry of the brain: how its systems shape our perceptions, emotions, actions, and reactions; how possession of this knowledge can enable us to more fully understand and improve our lives; and how the brain responds to the guidance of its user. He draws on examples from his own practice, from research, and from everyday life to illuminate aspects of the brain's functioning, among them prenatal and early childhood development; the perceptual systems; the processes of consciousness, memory, emotion, and language; and the social brain.
