Daniel Reisel is here to talk about our brains. In particular, how we might change them--and how this kind of thinking might just change the tenor of society as a whole.
He introduces us to Joe, who's 32, and a murderer. Reisel met Joe in Wormwood Scrubs, a high-security prison that houses England's most dangerous prisoners. On a grant from the UK Department of Health, Reisel visited the jail to study inmates' brains and try to find out what lay at the root of their behavior.
