Neuroscientist Adam Zeman on how amnesia leads to a loss of self and how the lives of two men, Peter and Marcus, have been affected by their lack of a past. As Professor of Cognitive and Behavioural Neurology at the University of Exeter, Adam works with people with epilepsy who experience loss of memory. His work leads him to examine how memories are formed and ask whether autobiographical details are the only part of our sense of self that matters.
