As a schoolboy, I vividly remember picking up a copy of Oliver Sacks’s book, The Man Who Mistook His Wife for a Hat. As I read these stories of a mariner unable to form new memories, of a man who could not recognise his own leg, of the woman who heard music as a result of epileptic seizures, I was gripped. But it was the context in which he put these symptoms, the impact on the lives of the human beings in front of him, that led to a deeper understanding of the nature of these conditions and how they affect us. And it was reading these stories that inspired my interest in neuroscience, and no doubt many of my colleagues too.
