In An Anthropologist on Mars Oliver Sacks uses case studies to illustrate the myriad ways in which neurological conditions can affect our sense of self, our experience of the world, and how we relate to those around us. Writing with his trademark blend of scientific rigour and human compassion, he describes patients such as the colour-blind painter or the surgeon with compulsive tics that disappear in the operating theatre; patients for whom disorientation and alienation – but also adaptation – are inescapable facts of life. 'An inexhaustible tourist at the farther reaches of the mind, Sacks presents, in sparse, unsentimental prose, the stories of seven of his patients. The result is as rich, vivid and compelling as any collection of short fictional stories' – Independent on Sunday Now part of the Picador Collection, a series showcasing the very best of modern literature.
