The ventral posterior lateral (VPL) nucleus of the thalamus serves as a key relay station for somatosensory information from the body, including the trunk and extremities.1

The medial lemniscus pathway conveys signals associated with light touch, pressure, and kinesthetic (positional) sense to the VPL nucleus. These signals originate from receptors in the body and are transmitted through the dorsal column system to the medulla oblongata before ascending via the medial lemniscus to the thalamus. Once received by the VPL nucleus, this information is projected in a topographically organized manner to the primary somatosensory cortex.123
