Location and Function
- Located in the caudal pons
- Group of second-order neurons
- Receives information about discriminative sensation and light touch of the face
- Receives conscious proprioception of the jaw
- Plays a role in sensory processing of the trigeminal nerve

Sensory Information
- Most sensory information crosses the midline
- Travels to the contralateral ventral posteromedial nucleus (VPM) of the thalamus
- First-order neurons of CN V transmit the information
- Involved in transmitting information about discriminative sensation and light touch of the face
- Involved in transmitting information about conscious proprioception of the jaw

Oral Cavity Information
- Information about the oral cavity travels to the ipsilateral VPM of the thalamus
- Transmitted via the dorsal trigeminothalamic tract
- Different pathway compared to other sensory information
- Important for processing sensory information related to the oral cavity
- Contributes to the overall sensory perception of the face

Anatomical Identifiers
- Latin term: nucleus principalis nervi trigemini
- NeuroNames identifier: 560
- TA98 identifier: A14.1.05.406
- TA2 identifier: 5932
- FMA identifier: 54533

Role in Neuroanatomy
- Part of the cranial nerve nuclei
- Schematically represented in the dorsal view
- Motor nuclei are represented in red, while sensory nuclei are represented in blue
- Plays a crucial role in sensory processing within the trigeminal nerve
- Contributes to the overall function and perception of the face and oral cavity
