Document Summary

Hypothalamus, anterior thalamic nuclei, cingulate gyrus, and hippocampus. Amygdala (primary structure in production and governance of emotion) Emotional behaviors-muscular changes appropriate to environmental context) Autonomic changes-additional energy available quickly and prepares for additional activity) Hormonal changes-production of hormones help sustain autonomic response. The main shit is that the amygdala runs the whole thing. Division of amygdala most relevant: medial nucleus, lateral and basolateral nucleus, central nucleus and basal nucleus. Sensory inputs go to amygdala from thalamus and sensory cortex, hippocampus (fear conditioning) Stimulates emotional response automatically (without cortical processing) Inputs from the orbital frontal cortex may be important for emotion based on social situations. Phineas gage fucked up his frontal cortex. Fully recovered by had personality changes (damaged ofc) Ofc patients have trouble making rational decisions about personal and social matters, changes in emotion processing. Ofc and anterior cingulate cortex are together called the ventromedial prefrontal cortex- serotonin is the main neurotransmitter; dopamine.
