Abstract
Split-brain patients, in whom the cortical commissures, principally the corpus callosum, have been cut, provide a unique window into functional specialization of each cerebral hemisphere. Early testing of these patients, using various methods for lateralizing stimulus input and responses, confirmed hemispheric specializations suspected from previous studies of patients with lateralized brain damage. The following decades produced many examples of functional differences between the two hemispheres in the attentional, perceptual, and cognitive domains. Comparisons of partial- and complete-callosotomy patients have yielded information about functionally specific pathways through the corpus callosum. Division of the brain has also provided insight into the nature of consciousness in each hemisphere.
