What is a split-brain?
Quick Answer
A split-brain refers to the condition after the corpus callosum is severed, usually to reduce severe epilepsy. It can reveal how the two hemispheres process information differently.
The Full Story
Split-brain studies became famous in the mid-20th century after surgeons cut the corpus callosum in some patients with severe epilepsy. Researchers such as Roger Sperry and Michael Gazzaniga showed that the left and right hemispheres can process information differently and that communication between them is normally essential. These studies helped transform understanding of lateralization, language, and consciousness. They remain a landmark in neuroscience and psychology.
