Dean Buonomano: Debugging the Brain

The most important computer we own is a three-pound, blandly coloured grey chunk of electrified flesh. This marvellous computer, the human brain, regulates our heart beat and allows us to taste ice cream, but it has its glitches or - as neurobiologist Dean Buonomano calls them - brain bugs. These bugs help explain our why we fear those different from us, influencing everything from who we vote for, to whether we go to war. Dean Buonomano, author of "Brain Bugs," sits down with Piya Chattopadhyay to discuss how we can fix these glitches.
