split-brain experiments

Split-brain experiments involve surgically severing the corpus callosum, the main nerve connection between the brain's two hemispheres. This procedure is used to study how each side of the brain functions independently. Researchers found that when the connection is cut, each hemisphere can operate separately, processing different information and controlling different actions. For example, if a word is shown only to the right eye (left hemisphere), a person can say it, but if it's shown only to the left eye (right hemisphere), they might recognize it but be unable to verbally identify it. These experiments reveal the specialized roles of each brain hemisphere.
