“When people have accidents that damage their frontal lobe or when they have a disorder or illness affecting the frontal lobe, their personality alters. Effectively, the Human part of the brain stops working and the new personality that presents is the Chimp. Very often, people affected in this way will become disinhibited and lose their judgment or they can become apathetic or have outbursts of aggressive behavior.”
