Document Summary
Sensory data comes in from brainstem along with emotional, visceral, and other info from different areas of the brain. Thalamus relays these messages to the appropriate areas of the cerebral cortex. Determines which signals require conscious awareness, and which should be available for learning and memory. Frontal lobe (prefrontal cortex) and mediodorsal (md) nucleus. Postcentral gyrus and ventral posterolateral (vpl) nucleus. Postcentral gyrus and ventral posteromedial (vpm) nucleus. Visual association cortex (parietal lobe) and pulvinar nucleus. Visual cortex and lateral geniculate (lg) nucleus. Auditory cortex and medial geniculate (mg) nucleus. Cerebellum (dentate nucleus) and ventrolateral (vl) nucleus. Basal ganglia (globus pallidus) and ventroanterior (va) nucleus. Limbic system and anterior (a) nucleus via mammillothalamic tract. Mammillary bodies receive input from the hippocampus. Does a diverse array of things - difficult to diagnose lesion here. Processes sensory impulses of smell, taste, vision. Regulates endocrine system and internal functions that sustain the body.
