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

Input and output[edit]

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[edit]

The ventral posterior nucleus is divided into^{[citation needed]}:

• Ventral posterolateral nucleus, which e.g. receives sensory information from the body.
• Ventral posteromedial nucleus, which e.g. receives sensory information from the head and face via the trigeminal nerve.

Function[edit]

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