* Bilateral amygdala destruction results in Klüver Bucy syndrome, which involves, most prominently, social tameness mixed with a loss of avoidance, manifesting with hypermetamorphosis (the incessant exploration of objects within the environment), hyperorality, visual agnosia, and hypersexuality.
Klüver Bucy syndrome was first described from the effects of bilateral amygdala and hippocampal destruction in monkeys, but it is a rare complication of a variety of naturally occurring illnesses in humans, including herpes simplex encephalitis, frontotemporal lobar dementia, and anoxicischemic lesions in the bilateral anterior medial temporal lobes.
