For thousands of years philosophers have tried and failed to come up with satisfactory answers to questions such as 'who am I?' and 'how does my biological brain make my subjective mind?'

In this thought-provoking programme Oxford University professor of mathematics Marcus du Sautoy takes a journey deep into his own brain - a willing guinea pig for some of the most extraordinary experiments known to neuroscience - to discover where 'free will' and 'self' actually come from.
