Amygdala is a part of the cerebellum in general and limbic system in particular. Findings by G.V. Goddar (1964) revealed that damage to the amygdala could turn a wild animal into a docile creature. In another study, Bard and Mountcastle (1948) demonstrated that damage to a part of the amygdala can turn a docile animal into an aggressive beast.

Goddard also found that by stimulating parts of the amygdala, mild and intense fears are licited. In intense fear, the animal flees from the spot in panic. Psychosurgery if amygdala is called "amygdalectomy". Malfunction of amygdala may trigger violent emotional reactions (Mark and Ervin, 1970).
