cortex, olfactory, limbic regions
Ventral Anterior basal ganglia premotor and motor areas
Ventral Lateral cerebellum, basal ganglia

Substantia nigra

motor area
Lateral Posterior
Ventral Lateral Posterior touch, pressure, pain, temperature area 1, 2, 3 postcentral gyrus
Pulvinar posterior cortex, superior colliculus posterior cortex, areas 17-18
Lateral Geniculate Body visual projections Area 17, Occipital cortex
