@@Home -> BiologicalLifeResearch -> BrainAreaLAC -> BrainRegionLAC_HT_BR


This page covers biological details of component Barrington's Nucleus. Region is part of aHuman target integrated biological model.

  • Top-down path to region: Hindbrain Metencephalon -> Metencephalic Motor Nuclei (HT.MN) -> Barrington's Nucleus (LAC.HT.BR) (see Mind Maps)
  • Type: nucleus
  • Quality: L0
  • Brain area: Lower Brain - Autonomous Control Area
  • Role: subcortical.motor.flexor
  • Function: Supraspinal regulation of urination
  • Comments: M-region, pontine micturition center (PMC)
  • Notes to function:
    • Sends projections to Sacral Precerebellar Nucleus
