Document Summary

Studies in humans and animals showed thalamus and hypothalamus involved. If they were damaged, they couldn"t generate an emotional response. Controls motor functions and hormonal responses (via pituitary). Projections from hypothalamus to spinal cord which controls autonomic ns responsible for visceral muscles and peripheral endocrine glands. Hypothalamus also has output to skeletal muscle so can induce behaviour e. g. in response to freezing. Hypothalamus takes different sensory inputs and selects appropriate motor behavior e. g. if a dog is aggressive it can increase blood pressure and heart rate through hypothalamus. Damage to limbic system causes deficits in emotional response. Limbic system refers to higher order cortical areas (cingulate cortex, prefrontal cortex) and the allocortex (older more primitive cortex) such as the amygdala and the hippocampus. Allocortex (found in more primitive animals where neocortex is less developed in humans) has projections to hypothalamus and other brainstem areas. Limbic loop formed by primitive cortex (allocortex: blue), with extensive connection to deep brain structures.
