Ventral posteromedial nucleus

From Wikipedia, the free encyclopedia

Brain: Ventral posteromedial nucleus
Thalamic nuclei: MNG = Midline nuclear group AN = Anterior nuclear group MD = Medial dorsal nucleus VNG = Ventral nuclear group VA = Ventral anterior nucleus VL = Ventral lateral nucleus VPL = Ventral posterolateral nucleus VPM = Ventral posteromedial nucleus LNG = Lateral nuclear group PUL = Pulvinar MTh = Metathalamus LG = Lateral geniculate nucleus MG = Medial geniculate nucleus
Latin	nucleus ventralis posteromedialis thalami

The ventral posteromedial nucleus (VPM) is a nucleus of the thalamus.

[edit] Inputs and outputs

It projects to the postcentral gyrus and receives the solitary tract and trigeminal nerve information from the medial lemniscus.
