This page covers biological details of component Caudal 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) -> Caudal Pontine Reticular Nucleus (LRC.HT.PRF.CRF) (see Mind Maps)
• Type: nucleus
• Quality: L0
• Brain area: Lower Brain - Motor Reflex Area (LRC)
• Area circuit: Breathing and Swallowing Reflexes (LRB)
• Role: subcortical.motor.flexor
• Function: Mediate head movements
• Notes to function:
  • Grinding of the teeth in sleep, projections from superior colliculus, to spinal cord, extends to facial
