Explanation:

Lobotomy is a psychosurgery that involves cutting nerve fibers in the brain. The lobotomy was based on the idea that mental illnesses can be cured by changing the way the brain works. It was believed that changing connections with the frontal lobes could change emotions without affecting intelligence. The most common procedure was the introduction of a sharp tool to reach the frontal lobe of the brain through the eye.

Lobotomy attempts to change the connections of white matter into gray matter. White matter has the nerve fibers that connect gray matter, which includes neurons or brain cells,  and carry messages with electrical impulses.
