 Thalamus function | relay ascending sensory information to cortex |
| Lateral geniculate nucleus | visual, projects via optic radiations to occipital cortex - lateral for light |
| Medial geniculate nucleus | auditory, Medial for Music |
| Ventral posterior nucleus, lateral part (VPL) | body sensation, proprioception, pressure, pain, touch, dorsal column tracts and spinothalamic tract |
| Ventral posterior nucleus, medial part (VML) | facial sensation (via CN V), taste, put makeup on face and it goes through vpM |
| Ventral anterior/lateral (VA/VL) nuclei | motor |
| Blood supply | Posterior communicating, posterior cerebral, ICA |
| Thalamic syndrome | vascular lesion with damage to VPL and VPM, contralateral sensory loss, decreased proprioception --> falls, no motor defects |
