Understanding functional and structural areas of the cerebral cortex is important to understand as it allows us to predict what behaviors might be affected with damage to a particular area. the damage might arise from stroke, trauma, or cancer.

It is important to study healthy individuals and individuals who have had injury to the cerebral cortex. You can compare healthy individuals (control group) to the people who have had damage to the brain. Studying people with damage to the brain can help us draw conclusions if there are any negative effects on mood or personality.
