This page covers biological details of component Lower Substantia Gelatinosa. Region is part of aHuman target integrated biological model.
- Top-down path to region: Spinal Cord -> Posterior/Dorsal Horn (BMA.SC.PH) -> Lamina II (LPC.SC.PH.L2) -> Substantia Gelatinosa (LPC.SC.PH.SG) -> Lower Substantia Gelatinosa (LPC.SC.PH.LSG) (see Mind Maps)
- Type: nucleus
- Quality: L0
- Brain area: Lower Brain - Peripheral Control Area (LPC)
- Area circuit: Lower Body Conscious Sensations (SBL)
- Role: sensory.nucleus
- Function: Relay for C-fibers of slowly conducting, poorly localized pain sensation - T7-T12,L1-L5,S1-S5,CX
