Split brain surgery involves:

Split brain surgery involves:

• A. Severing the corpus callosum and disconnecting the two hemispheres.
• B. Removing the frontal lobes to reduce aggression.
• C. Stimulating the limbic system to improve memory.
• D. Repairing damaged brain tissue after injury.

Answer: (A)

Split-brain surgery demonstrates what happens when the two halves of the brain are no longer able to communicate. It works by severing the corpus callosum, the large bundle of nerve fibers that connects the left and right hemispheres. By cutting this bridge, epileptic activity has difficulty spreading from one hemisphere to the other, which can reduce seizure severity or frequency while leaving much of the brain intact. Because the hemispheres can’t easily share information after the cut, each side may handle tasks differently. For example, language tends to be localized in the left hemisphere for many people, so information processed in the right hemisphere isn’t as readily verbalized. This illustrates how localization and interhemispheric communication shape our thinking and behavior. The other options describe different procedures or goals. Removing frontal lobes would be a lobotomy, not split-brain surgery. Stimulating the limbic system targets emotion or memory rather than disconnecting the hemispheres. Repairing damaged brain tissue is a general approach to injury, not the specific method used to create a split-brain state.
