In the early 1960’s, Roger W. Sperry and Michael Gazzaniga worked together to explore the brain and its’ functions. They wanted to study the right and left side of the brain separately, and explore the idea of each side functioning independently. The study took place at the California Institute of Technology. Human participants, who experienced rare and very extreme cases of epilepsy, went under surgery to sever the corpus callosum. When the corpus callosum is cut, communication between the right and left hemispheres is disrupted, leaving each half to function separately. After the operation, the participants underwent three different tests to study different mental and perceptual capabilities. These tests measured their visual, tactile,
