The ventral posterior nucleus is the somato-sensory relay nucleus in
thalamusof 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.
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.
touch, body position, pain, temperature, itch, taste, and arousal.
