| | + | In 1939, researches found that monkeys with a large amount of their temporal lobes removed, including the amygdala. They were no longer afraid of [[snake]]s and [[human]]s, which are normal fear-provoking stimuli. This effect is known as the Klüver-Bucy syndrome.<ref>Klüver, H., & Bucy, P.C. (1939).

| | + | This has also been observed in [[rat]]s and humans. Rats with damaged amygdala showed no fear when placed next to a cat.<ref>Maren, S., and Faneslow, M.S. (1996). The amygdala and fear conditioning: Has the nut been cracked? ''Neuron, 16'', 237-240</ref> |
