Who's in Charge?: Free Will and the Science of the Brain

Publishers WeeklyAre our actions determined solely by physical processes, or is the mind its own master? This age-old philosophical conundrum gets a terrific, if ultimately indecisive, analysis in this engrossing study of the mechanics of thought. Gazzaniga (Human: The Science Behind What Makes Your Brain Unique), a leading cognitive neuroscientist, draws on cutting-edge research, including his fascinating experiments with "split-brain" patients, to diagram the Rube Goldberg apparatus inside our skulls. Beneath our illusion of an in-control self, he contends, thousands of chaotically interacting neural modules governing motion, senses, and language unconsciously make decisions long before we consciously register them; the closest thing to a self is a brain module called "the interpreter," which spins a retrospective story line to rationalize whatever the nonconscious brain did.
