Document Summary

Limbo (border) with brainstem; top of the brain stem. Rage/fear (attack/defense) rabies virus affects limbic cortex: bouts terror, rage. Cingulate cortex: emotional component (lesion in c. cortex: feel pain but not bothered by it) Somatosensory only cares about pain l, i, t if there"s a lesion here, still feel pain or. Chronic lesion in c. cortex patients are constantly bothered by pain emotional aspects of pain bc this is sent to limbic system. Many structures project to and from the hypothalamus. Information entering the hypothalamus: retina visual information (circadian rhythms, thalamus sensory info from entire body & environment, circulating blood hypothalamus has a bunch of receptors for osmo, gluco, Signals size of fat stores; large fat stores hypothalamus will signal. Leptin: hormone made in fat storage cells, released into the blood and for a reduction in motivated behavior of food intake sodium, leptin, etc goes into hypothalamus.
