This page covers biological details of component Pontine Reticulotegmental 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, Lateral Column (HT.RF.LAT) -> Pontine Reticulotegmental Nucleus (LLC.HT.PRF.RTMG) (see Mind Maps)
  • Type: nucleus
  • Brain area: Lower Brain - Locomotion Control Area
  • Role: processor.automatic
  • Function: Mediate saccadic eye movements
  • Notes to function: Inactivation leads to deficit of expression, but not learning
