Ventral posterior nucleus
Lua error in package.lua at line 80: module 'strict' not found. Lua error in Module:Infobox at line 235: malformed pattern (missing ']'). The ventral posterior nucleus is the somato-sensory relay nucleus in thalamus of the brain.
Input and output
The ventral posterior nucleus receives neuronal input from the medial lemniscus, spinal lemniscus, spinothalamic tracts, and trigeminothalamic tract. It projects to the somatosensory cortex and the ascending reticuloactivation system.
Subdivisions
The ventral posterior nucleus is divided into:[citation needed]
- Ventral posterolateral nucleus, which receives sensory information from the body.
- Ventral posteromedial nucleus, which receives sensory information from the head and face via the trigeminal nerve.
Function
Functions in touch, body position, pain, temperature, itch, taste, and arousal.
