Lateral geniculate
Medial geniculate
ventral posterior medial of thalamus (VPM)
sensory of face
sensory from arms and lets (from thalamus)
VPL-Ventral posterior lateral
sesnory from eyes (thalamus)
lateral geniculate
sensory from ears (thalamus)
medial geniculate
part of brain for intellect and association
cerebrum
hunger, thirst, temperature regulation, sex, rage, fear
hippocampus
balance, equilibrium, involuntary corrdination, unconscious proprioception
cerebellum
inhibits thalamus by stopping motor response and providing background muscle tone
Basal Ganglia
wernicke’s area is destroyed by
B1/thiamine deficiency (alchoholism-wernike korsakoff syndrome)
found in the junction of the parietal, occipital and temporal lobe
wernicke’s area

Occipital lobe
localization “somesthetic cortex”
Parietal lobe
hearing/superior lobe
temporal
voluntary motor is part of the _____ in the _____ lobe
precentral gyrus
frontal
associated with the amygdala. Pleasure or pain? Do I need for survival?
limbic system
dysfunction in the basal ganglia ::(trivial info illicit a motor response)
parkinson’s disease (forms lewy bodies from decreased dopamine levels) “cog wheel deformity”
caudate nucleus (part of bass ganglia) secretes
GABA
consists of the putamen + caudate
striatum (internal capsule separates caudate and putamen)
inclusion bodies aka
lewy bodies parkinsons
