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

• Top-down path to region: Spinal Cord -> Posterior/Dorsal Horn (BMA.SC.PH) -> Lamina I (LPC.SC.PH.L1) -> Marginal Nucleus (LPC.SC.PH.MG) -> Upper Marginal Nucleus (LPC.SC.PH.UMG) (see Mind Maps)
• Type: nucleus
• Quality: L0
• Brain area: Lower Brain - Peripheral Control Area (LPC)
• Area circuit: Upper Body Conscious Sensations (SBU)
• Role: sensory.nucleus
• Function: Relay information related to pain and temperature sensation - C1-C8,T1-T6
