Definition

The trigeminal lemniscus is a part of the brain that conveys tactile, pain, and temperature impulses from the skin of the face, the mucous membranes of the nasal and oral cavities, and the eye, as well as proprioceptive information from the facial and masticatory muscles. It is the ascending axonal tract in the brainstem that carries tactile and proprioceptive information from the contralateral principal nucleus of the trigeminal system to the ventral posterior medial nucleus of the thalamus. This tract is sometimes considered a cephalic division of the medial lemniscus.
