Detailed and fascinating portraits of seven neurological patients, including a surgeon consumed by the compulsive tics of Tourette's syndrome unless he is operating; an artist who loses all sense of color in a car accident, but finds a new sensibility and creative power in black and white; and an autistic professor who cannot decipher the simplest social exchange between humans, but has built a career out of her intuitive understanding of animal behavior. "Among doctors who write with acuity and grace, Sacks ( The Man Who Mistook His Wife for a Hat) takes a higher place with each successive book.... enlarges our view of the nature of human experience." --Publisher's Weekly "... Dr. Sacks's best book to date." --The New York Time Book Review
