Study Notes
The Role of Hypothalamus and Amygdala in Emotional Behavior
- Hypothalamus plays a critical role in the integration of emotional states, with examples of "sham rage" observed in cats with intact hypothalamus
- "Uninhibited hypothalamic discharge" in humans can be caused by hypothalamic lesions, carbon monoxide poisoning, and hypoglycemia
- Electrical stimulation of different parts of the hypothalamus can elicit rage responses, attack behavior, or defensive postures resembling fear
- The limbic lobe, consisting of the cingulate and parahippocampal gyrus, forms a rim around the corpus callosum and is part of the limbic system
- The limbic system includes the amygdala, which links cortical sensory regions with the hypothalamus and brainstem, and plays a role in mediating emotional behavior
- Klüver–Bucy syndrome, resulting from bilateral lesions of the medial temporal lobe, demonstrates visual agnosia, docility, hyperphagia, hyperorality, and hypersexuality
- The amygdala has three major functional and anatomical subdivisions: central, medial, and basolateral, each with specific connections and functions
- Unilateral lesion of the amygdala in monkeys resulted in changes in behavior, demonstrating the role of the amygdala in interpreting the significance of visual stimuli
- The amygdala is involved in the association of neutral stimuli with primary reinforcers, contributing to associative learning
- Patient S.M., suffering from Urbach-Wiethe disease with amygdala calcification and atrophy, cannot recognize the emotion of fear, highlighting the role of the amygdala in fear processing and recognition
