I was really charmed by the anecdotes Michael Gazzaniga shared in a recent New York Times profile (http://www.nytimes.com/2011/11/01/sci... especially the story about how "Yellow Submarine" disrupted a particularly important experiment. I was also intrigued a piece he wrote in TIME magazine about Jared Loughner's case. (http://ideas.time.com/2011/11/22/was-...) This book was a disappointment, though. Gazzaniga's impressive career includes some key research on the left and right brain (explained nicely in this book). But the book doesn't really deliver on its promise to dive deeply into questions of how brain science has/will/should play a role in our notions of free will and responsibility, especially in the criminal justice system. A lot of ideas are hinted at or sketched out but I was hoping for a richer exploration of these themes than the book really offered.
