split-brain theory

The split-brain theory arises from research on patients who have had the corpus callosum—connecting the left and right brain hemispheres—severed to treat severe epilepsy. This division results in each hemisphere operating independently, leading to surprising effects. For instance, the right hemisphere can process visual information but struggles with language, while the left can articulate thoughts but may not recognize objects presented only to the right side. This research has deepened our understanding of how different brain regions specialize in various functions and how they communicate, highlighting the complexities of human cognition.
