	While at Caltech, Sperry pursued his interest in the routes by which information is transferred from one side of the cerebral cortex to the other. After a series of experiments, Sperry and his colleagues discovered two possible routes for such interhemispheric transfer—the corpus callosum and the optic chiasm. However, he found that ablating both the corpus callosum or the optic chiasm before training did not interfere with transfer. A brain that has had its corpus callosum and its optic chiasm ablated is referred to as a split-brain preparation.
