This page covers biological details of component Upper 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) -> Upper Substantia Gelatinosa (LPC.SC.PH.USG) (see Mind Maps)
  • Type: nucleus
  • Brain area: Lower Brain - Peripheral Control Area
  • Role: sensory.nucleus
  • Function: Relay for C-fibers of slowly conducting, poorly localized pain sensation - C1-C8,T1-T6
