Kluver-Bucy syndrome - definition
syndrome identified by Heinrich Klüver and Paul Bucy in the 1930s when they removed the temporal lobes of monkeys. The syndrome is characterized primarily by a reduced level of aggression and reduced expression of fear. The monkeys also displayed hypersexuality, an increased propensity to place objects in their mouths, and a number of other behaviors. It was later discovered that many of the changes regarding fear expression were attributable to removal of the amygdala.
