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.
| Property | Value |
|---|---|
| Category | Brainstem / Trigeminal Sensory |
| Location | Medulla to C2 spinal cord |
| Function | Face pain, temperature, touch from orofacial region |
| Diseases | Trigeminal Neuralgia, Migraine, MS, Brainstem Stroke |
The SpV is divided into three subnuclei:
Research on Spinal Trigeminal Nucleus has revealed important implications for neurodegenerative diseases.
The study of Spinal Trigeminal Nucleus (Spv) has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.

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.
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.
Rat and mouse models of orofacial pain have identified key neuronal populations in SpV that mediate inflammatory and neuropathic pain states.
