Pioneer of research into the split brain, Dr Michael Gazzaniga

Dr Michael Gazzaniga has lead pioneering studies on patients with split brains, where the two hemispheres work completely separately from eachother. In the 1960's he was involved in studies of split brained patients, people who as a result of their conditions could draw two different objects at the same time with each hand. Sometimes one side of the brain would work in opposition to the other - one hand would reach out to open a car door while the other would try to stop that hand from opening the door.
