This page covers biological details of component Kolliker-Fuse Nucleus. Region is part of aHuman target integrated biological model.

  • Top-down path to region: Hindbrain Metencephalon -> Metencephalic Motor Nuclei (HT.MN) -> Kolliker-Fuse Nucleus (LRC.HT.KFN) (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: Control of protruder tongue muscles contraction to maintain respiration
  • Notes to function:
    • To hypoglossal nucleus and phrenic nucleus
    • pontine respiratory group = KFN + Medial PBN
