@@Home -> BiologicalLifeResearch -> BrainAreaLRC -> BrainRegionLRC_HT_PRF_RPO


This page covers biological details of component Oral Pontine Reticular Nucleus. Region is part of aHuman target integrated biological model.

  • Top-down path to region: Hindbrain Metencephalon -> Pontine Reticular Formation (HT.RF) -> Pontine Reticular Formation, Medial Column (HT.RF.MED) -> Paramedian Pontine Reticular Formation (HT.PRF.PPRF) -> Oral Pontine Reticular Nucleus (LRC.HT.PRF.RPO) (see Mind Maps)
  • Type: nucleus
  • Brain area: Lower Brain - Motor Reflex Area
  • Role: subcortical.motor.flexor
  • Function: Mediation of changing to and from REM sleep
  • Notes to function: Part of horizontal gaze center, projects to spinal cord and abducens; excites spinal extensors, inhibit flexors
