1. Can we boost the brain through diet? What is the reason for our existence?

We announce groundbreaking new findings and in the process improve our understanding of behaviour and pinpoint new ways to help boost brain power. Guests include Andrea Brand, the acclaimed biologist who developed a pioneering technique which allows scientists to peer into the brain as never before. We join Daniel Wolpert, a world leading computational scientist and a self proclaimed movement chauvinist - he argues that our sole reason for being is to move. Plus we discuss, with John O'Keefe and Edvard Moser, how winning a Nobel Prize has changed their lives.
