The ventral posterior nucleus is the somato-sensory relay nucleus in thalamus of the brain.

Input and output

It receives neuronal input from the medial lemniscus, spinal lemniscus, spinothalamic tracts, and trigeminothalamic tract (analogous to spinothalamic tract (which is below the face)). Outputs to the somatosensory cortex and the ascending reticuloactivation system.

ubdivisions

The ventral posterior nucleus is divided into:
*Ventral posterolateral nucleus, which e.g. receives sensory information from the lower part of the body.
*Ventral posteromedial nucleus, which e.g. receives sensory information from the head via the trigeminal nerve.

Function

Functions in touch, body position, pain, temperature, itch, taste, and arousal.
