Trigeminal lemniscus

The lemniscus trigeminal nerve is a fiber tract in the brain represents the information of tactile perception and deep sensibility of the face from the fifth cranial nerve ( trigeminal nerve ) or its cranial nerve nucleus (nucleus principalis trigeminal ) to the corresponding nucleus of the thalamus ( ventral posteromedial nucleus, VPM ) is derived. He rearranges the medial lemniscus to, the information of the same qualities of all the other parts of the body from the spinal cord to the thalamus passes. As it crosses before reaching the thalamus to the opposite side, so that the information is always reach a side of the face only the thalamus of the other body. Sometimes the trigeminal lemniscus is also known as the cephalic portion of the medial lemniscus considered, as it contains information from the head area.

The VPM shall transmit the information of the trigeminal lemniscus together with those of the lemniscus medialis then the somatosensory cortex ( postcentral gyrus ) of the cerebral cortex.

In addition there exists the lateral lemniscus, which is part of the auditory pathway.
