Professor Guy Leschziner's new book, The Man Who Tasted Words, seeks to shed light on our experiences of the different senses. In the book, Guy meets individuals such as Valeria, for whom music is accompanied by colours and James, after which the book is named: a man who tastes words. The new title follows Guy's previous book on the mysteries of sleep, The Nocturnal Brain. He joins broadcaster, author and science communicator Helen Czerski to talk about it all.
