Weighing a mere three pounds, the human brain is truly a wonder of design and function. Mysteries of the Mind explores all aspects of this most fascinating organ -- its structure and how it works, the effects of genetics and experience, the biology behind emotion and memory,as well as what happens when things go wrong. Continuing a National Geographic tradition for illustrating and clearly explaining the life sciences, Mysteries of the Mind was written by Richard Restak, M.D., a best-selling author and a national authority on the brain.
