The amygdala is a structure in the temporal lobe of the cerebral hemisphere. It is part of the limbic system.[1][2]
Amygdala damage
In 1939, researches found that monkeys with a large amount of their temporal lobes removed, including the amygdala. They were no longer afraid of snakes and humans, which are normal fear-provoking stimuli. This effect is known as the Klüver-Bucy syndrome.[3]
This has also been observed in rats and humans. Rats with damaged amygdala showed no fear when placed next to a cat.[4]
