Unthinkable Helen Thomson

IMAGINE . . . getting lost in a one-room flat; seeing auras; never forgetting a moment; a permanent orchestra in your head; turning into a tiger; life as an out-of-body experience; feeling other people's pain; being convinced you are dead; becoming a different person overnight.

Our brains are far stranger than we think. We take it for granted that we can remember, feel emotion, navigate, empathise and understand the world around us, but how would our lives change if these abilities were dramatically enhanced - or disappeared overnight?

Award-winning science writer Helen Thomson has spent years travelling the world tracking down incredibly rare brain disorders. In Unthinkable she tells the stories of nine extraordinary people. From the man who thinks he's a tiger to the doctor who feels the pain of others just by looking at them, their experiences illustrate how the brain can shape our lives in unexpected and, in some cases, brilliant and alarming ways.

Delving into the rich histories of these conditions, exploring the very latest research and cutting-edge medical techniques, Thomson explains the workings of our consciousness, our emotions, our creativity and even the mechanisms that allow us to understand our own existence.
