@@Home -> BiologicalLifeResearch -> BrainAreaLPC -> BrainRegionLPC_PN_SG_UDRG

This page covers biological details of component Upper Dorsal Root Ganglion. Region is part of aHuman target integrated biological model.

Top-down path to region: Peripheral Nervous System -> Sensory Ganglia (PNS.SG) -> Dorsal Root Ganglia (LPC.PN.SG.DRG) -> Upper Dorsal Root Ganglion (LPC.PN.SG.UDRG) (see Mind Maps)
Type: sensory ganglion
Quality: L0
Brain area: Lower Brain - Peripheral Control Area (LPC)
Area circuit: Upper Body Conscious Sensations (SBU)
Role: sensory.ganglion
Function: Integration of afferent signaling from cervical and upper thoracic somatic and viscera
Notes to function:
- C1-C8, T1-T6
