Dorsal trigeminal tract

The posterior trigeminothalamic tract (or dorsal trigeminothalamic tract) is composed of second order neuronal axons. These fibers carry sensory information about discriminative touch and conscious proprioception in the oral cavity from the principal (chief sensory) nucleus to the ventral posteromedial (VPM) nucleus of the thalamus.

The posterior trigeminothalamic tract is also called the posterior trigeminal lemniscus.
