Sperry, the first to study split brains in humans, found that several patients who had undergone a complete calloscotomy suffered from split-brain syndrome. Michael Gazzaniga is the Director of the SAGE Center for the Study of Mind at the University of California, Santa Barbara. The results of these The study showed that subjects were significantly more efficient in determining the nature of the string of letters when the information was fed directly to the left hemisphere via the right eye. The content of this field is kept private and will not be shown publicly. hemispheres. With the help of so called "split brain" patients, he carried out experiments (just like the one you can perform by yourself in the Split Brain Experiments Game), and for the first time in history, knowledge about the left and right hemispheres was revealed. This can give rise to a kind of split personality, in which the left hemisphere give orders that reflect the person’s rational goals, whereas the right hemisphere issues conflicting demands that reveal hidden desires. In the 1960s, Sperry was joined by Michael Gazzaniga, a psychobiology Ph.D. student at Caltech. Roger Sperry was born on August 20, 1913 in Hartford, Connecticut. The procedure involves severing the corpus callosum, the main bond between the brain’s left and right hemispheres. When they posed the same question to the left, however, he responded, "a draftsman."
