A history of the brain. Part 5, The spark of being.

The fifth in a ten-part series in which Dr Geoff Bunn journeys through 5000 years of our understanding of the brain. In this part, he focuses on the role of electricity in the brain as a means of communication both within the brain and with the rest of the body. As part of the programme, actors read extracts from those who have written about the brain across the ages and an imaginary anatomy lesson takes place, this week focusing on the Corpus Callosum.
