Kliiver-Bucy syndrome is associated with lesion in the following area of brain
**Core Concept**
Kluver-Bucy syndrome is a neurobehavioral disorder characterized by a set of abnormal behaviors, including hypersexuality, hyperorality, and placidity, in response to environmental stimuli. This condition occurs due to bilateral damage to specific structures in the temporal lobe.
**Why the Correct Answer is Right**
The amygdala plays a crucial role in processing emotions, particularly fear and aggression. Damage to the amygdala disrupts this emotional processing, leading to a loss of fear and aggression responses, which is a hallmark of Kluver-Bucy syndrome. The amygdala is also involved in the processing of social and emotional information, and its damage can result in social withdrawal and changes in behavior.
**Why Each Wrong Option is Incorrect**
**Option B:** The cerebral cortex is responsible for processing sensory information, controlling movement, and facilitating thought, perception, and memory. While the cerebral cortex is involved in various higher-order cognitive functions, it is not directly associated with the behaviors observed in Kluver-Bucy syndrome.
**Option C:** The hippocampus is a structure involved in memory formation and spatial navigation. Damage to the hippocampus can lead to anterograde amnesia and difficulties with learning new information, but it is not directly associated with the behavioral changes observed in Kluver-Bucy syndrome.
**Option D:** The mammillary bodies are part of the limbic system and are involved in memory formation and spatial navigation. While the mammillary bodies are affected in Korsakoff's syndrome, they are not directly associated with the behaviors observed in Kluver-Bucy syndrome.
**Clinical Pearl / High-Yield Fact**
Kluver-Bucy syndrome is often seen in patients with temporal lobe damage, particularly those with bilateral amygdala lesions. This condition highlights the importance of the amygdala in processing emotions and social information, and its dysfunction can lead to significant behavioral changes.
**✓ Correct Answer: A. Amygdala**
