"You are your brain," insists Baylor University neuroscientist and best-selling writer David Eagleman.

It's an insight that he argues should radically transform all aspects of our criminal justice system, from how laws are written to how punishments are levied to how juries are selected.

Reporting back from the bleeding edge of brain research, Eagleman takes viewers on a tour of the latest technological insights into how humans make decisions and whether free will exists anywhere but the pages of philosophy books.

The findings don't exculpate individuals from responsiibility for their actions, the libertarian author of Sum: 40 Tales From The Afterlives says, but they certainly complicate things. And they help to explain why governments double or triple down on failed policies such as drug prohibition.
