Several neurological mysteries of the human brain get treated with a compassionate, highly fascinating, and very readable touch. Dr. Sacks describes a number of different cases wherein a patient loses a critical function of their mind. One woman, when her hands are placed behind her back... well, you need to read about this for yourself. What I love is that Oliver Sacks is a terrific writer, so his work in the hospital becomes a literary treat for me. Plus, his patients become lovable and uniquely human.
