Spinal Trigeminal Nucleus (Spv) is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The Spinal Trigeminal Nucleus (SpV) is the principal sensory nucleus for pain and temperature from the face. It extends from the pons to the cervical spinal cord and is organized somatotopically.

Pain Transmission Pathways
The spinal trigeminal nucleus receives pain and temperature afferents from the face via the trigeminal nerve (CN V). Second-order neurons project to the ventral posteromedial nucleus (VPM) of the thalamus, which then projects to the primary somatosensory cortex.
Clinical Relevance
Trigeminal neuralgia (tic douloureux) involves dysfunction of the trigeminal nerve and its central connections in the SpV. Surgical interventions and medications targeting sodium channels can provide relief.
Animal Models
Rat and mouse models of orofacial pain have identified key neuronal populations in SpV that mediate inflammatory and neuropathic pain states.
