A physician, professor of neurology and author, Oliver Sacks (1933-2015) has been described by the New York Times as 'a kind of poet laureate of contemporary medicine'. His books are made up of case histories of his patients, and explore both their neurological disorders and the strategies they adopted to cope with them.In Seeing Voices, a journey into the world of the profoundly deaf, Sacks examines the consequences of living in silence, including the different ways in which the deaf and the hearing learn to categorize and convey the experience of their respective worlds.
