Michael Gazzaniga: Split brains and other heady tales (highlight from the archives)

Beyond the hype of left brain versus right brain lies the work of acclaimed neuroscientist Michael Gazzaniga. His career was forged in the lab of Nobel laureate Roger Sperry, and together their trailblazing experiments have illuminated the differences between the brain's two hemispheres. Today he's on the US President's Bioethics Council, heads up a major project on neuroscience and the law, and is a prolific writer of popular neuroscience.
