@@Home -> BiologicalLifeResearch -> BrainAreaLPC -> BrainRegionLPC_HT_PN_PTR

This page covers biological details of component Principal Trigeminal Nucleus. Region is part of aHuman target integrated biological model.

• Top-down path to region: Hindbrain Metencephalon -> Metencephalic Sensory Nuclei (HT.SN) -> Pontine Nuclear Complex (HT.PN) -> Principal Trigeminal Nucleus (LPC.HT.PN.PTR) (see Mind Maps)
• Type: nucleus
• Brain area: Lower Brain - Peripheral Control Area
• Role: sensory.nucleus
• Function: Facial Somatic Sensations
• Notes to function: Upper, maxillary, ophthalmic
