Oliver Sacks was born in 1933 in London and was educated at Queen’s College, Oxford. He completed his medical training at San Francisco’s Mount Zion Hospital and at UCLA before moving to New York, where he soon encountered the patients whom he would write about in his book Awakenings.

Dr Sacks spent almost fifty years working as a neurologist and wrote many books, including The Man Who Mistook His Wife for a Hat, Musicophilia, and Hallucinations. The New York Times referred to him as ‘the poet laureate of medicine.’ His memoir, On the Move, was published shortly before his death in August 2015.

The River of Consciousness is a remarkable culmination of a lifetime’s research into the way the brain works by the celebrated late neurologist Oliver Sacks.
