Before Sperry's experiments, some research evidence seemed to indicate that areas of the brain were largely undifferentiated and interchangeable. In his early experiments Sperry challenged this view by showing that after early development circuts of the brain are largely hardwired.

In his Nobel-winning work, Sperry separated the corpus callosum, the area of the brain used to transfer signals between the right and left hemispheres, to treat epileptics. Sperry and his colleagues then tested these patients with tasks that were known to be dependant on specific hemispheres of the brain and demonstrated that the two halves of the brain now had independent consciousnesses.
