The principal sensory nucleus of trigeminal nerve (or chief sensory nucleus of V, main trigeminal sensory nucleus) is a group of
second-order neurons which have cell bodies in the caudal pons
.
It receives information about discriminative sensation and light touch of the face as well as conscious
CN V
.
- Most of the sensory information crosses the midline and travels to the anterior trigeminothalamic tract.
- However, information of the oral cavity travels to the ipsilateral VPM of the thalamus via the dorsal trigeminothalamic tract.
