@@Home -> BiologicalLifeResearch -> BrainAreaLPC -> BrainRegionLPC_HL_TGS_STR
This page covers biological details of component Spinal Trigeminal Nucleus. Region is part of aHuman target integrated biological model.
- Top-down path to region: Hindbrain Myelencephalon -> Myelencephalic Sensory Nuclei (HL.SN) -> Trigeminal Sensory Nuclei (HL.TGS) -> Spinal Trigeminal Nucleus (LPC.HL.TGS.STR) (see Mind Maps)
- Type: nucleus
- Quality: L0
- Brain area: Lower Brain - Peripheral Control Area (LPC)
- Area circuit: Sensory Face (SF)
- Role: sensory.nucleus
- Function: Discriminative sensation and light touch of face, conscious proprioception
- Notes to function:
- Pontine Nuclei, part of cranial nerve nuclei, ear, similar to SG of spinal cord
