Final answer:
The split-brain procedure involves severing the corpus callosum to treat severe epilepsy. It allows researchers to study the unique functions of each hemisphere of the brain.
Step-by-step explanation:
The corpus callosum, a bundle of nerve fibers that connects the brain's two hemispheres, is severed during the split-brain surgery. When no other treatment options are available for severe epilepsy, this surgery is usually utilized to treat it. The two hemispheres of the brain can be effectively segregated from one another by chopping the corpus callosum, which enables researchers to examine the distinct roles played by each hemisphere. Interesting behaviors can be displayed by split-brain patients, such as the inability to name objects presented in their left visual field with words but the ability to pick them up with their left hand.
In summary, during the split-brain procedure, the corpus callosum is severed. This procedure is used in cases of severe epilepsy that cannot be controlled through other methods.
