Oliver Sacks' The Man Who Mistook His Wife for a Hat tells the stories of individuals afflicted with fantastic perceptual and intellectual aberrations: patients who have lost their memories and with them the greater part of their pasts; who are no longer able to recognize people and common objects; who are stricken with violent tics and grimaces or who shout involuntary obscenities; whose limbs have become alien; who have been dismissed as retarded yet are gifted with uncanny artistic or mathematical talents.

To these seven narratives of neurological disorder Dr. Sacks brings the same humanity, poetic observation, and infectious sense of wonder that are apparent in his bestsellers Awakenings and The Man Who Mistook His Wife for a Hat. These men, women, and one extraordinary child emerge as brilliantly adaptive personalities, whose conditions have not so much debilitated them as ushered them into another reality.

In The River of Consciousness, Dr. Sacks takes on evolution, botany, chemistry, medicine, neuroscience and the arts and calls upon his great scientific and creative heroes - above all, Darwin, Freud and William James. For Sacks these thinkers were constant companions from an early age; the questions they explored - the meaning of evolution, the roots of creativity and the nature of consciousness - lie at the heart of science and of this audiobook.

Have you ever seen something that wasn't really there? Heard someone call your name in an empty house? Sensed someone following you and turned around to find nothing? Dr Oliver Sacks weaves together stories of his patients and of his own mind-altering experiences to illuminate what hallucinations tell us about the organisation and structure of our brains, how they have influenced every culture's folklore and art and why the potential for hallucination is present in us all, a vital part of the human condition. 

Imaginative and insightful, Seeing Voices offers a way into a world that is, for many people, alien and unfamiliar - for to be profoundly deaf is not just to live in a world of silence but also to live in a world where the visual is paramount. In this remarkable book, Oliver Sacks explores the consequences of this, including the different ways in which the deaf and the hearing impaired learn to categorise their respective worlds - and how they convey and communicate those experiences to others.
