Earlier conceptions of mental illness were attributed to neuronal oddities in the frontal lobe. Individuals consequently underwent surgical procedures in which parts of the frontal lobe were cut or scraped away.

Neuronal Oddities

Unusual or atypical characteristics or behaviors of neurons.

Frontal Lobe

The region of the brain located at the front of each cerebral hemisphere, responsible for problem solving, judgment, motor function, and behavior.

Surgical Procedures

Medical operations performed by cutting into the body to diagnose, treat, or prevent illness, repair damage, or replace defective parts or organs.
