Dr. Geoff Bunn presents a journey through 5000 years of our understanding of the most complex thing in the known universe: the brain, in this major ten-part BBC Radio 4 series.

In Episode 2, 'The Blood of The Gladiators', the focus is Ancient Greek scholarship, with Hippocrates' astonishingly prescient belief in the brain as the chief organ of control and his debunking of the myth of the 'sacred disease' with his assertion that epilepsy was the result of natural causes. Yet the belief that a cure lay in the magical properties of blood persisted for centuries.

The series is entirely written and presented by Dr Geoff Bunn of Manchester Metropolitan University, with actors Paul Bhattacharjee and Jonathan Forbes providing the voices of those who have written about the brain from Ancient Egypt to the present day, and actor Hattie Morahan giving the Anatomy Lesson which establishes the part of the brain to be highlighted in each episode – in this instance the cerebrum and cerebellum. The original, atmospheric score is supplied by composer, Barney Quinton. Producer: Marya Burgess.
