Input and output

The ventral posterior nucleus receives neuronal input from the medial lemniscus, spinothalamic tracts, and trigeminothalamic tract. It projects to the somatosensory cortex and the ascending reticuloactivation system.


The ventral posterior nucleus is divided into:


Functions in touch, body position, pain, temperature, itch, taste, and arousal. Modulates tremor in certain pathology.
