Question

In a split-brain procedure, the frontal cortex is surgically removed.

Answer 1

False

Step-by-step explanation:

• In a split-brain procedure, it is not the frontal cortex that is surgically removed. Instead, the procedure involves cutting the corpus callosum, a bundle of nerve fibers that connects the two hemispheres of the brain. This surgery is typically performed as a treatment for severe epilepsy when other methods of controlling seizures have failed.
• The purpose of cutting the corpus callosum is to prevent the spread of epileptic activity from one hemisphere of the brain to the other. By disconnecting the two hemispheres, the procedure can reduce the severity and frequency of seizures. However, it can also lead to a phenomenon known as "split-brain," where the two hemispheres of the brain are no longer able to communicate effectively with each other.
• It's important to note that the frontal cortex is a crucial part of the brain involved in various higher cognitive functions, including decision-making, personality, and social behavior. Surgical removal of the frontal cortex (frontal lobectomy) would have severe and debilitating effects on a person's cognitive and emotional functioning and is not a common procedure for epilepsy or any other medical condition.
• Instead, the focus in epilepsy surgery is typically on disconnecting the two hemispheres by cutting the corpus callosum while preserving the individual functions of each hemisphere to the extent possible.
