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

  • Top-down path to region: Midbrain Mesencephalon -> Reflexes Nuclei of Midbrain Mesencephalon (MM.REF) -> Visual Reflexes Nuclei of Midbrain Mesencephalon (MM.REF.VIS) -> Supraoculomotor Area (VBA.MM.SOA) -> Cajal Nucleus (LRC.MM.CJ) (see Mind Maps)
  • Type: nucleus
  • Brain area: Lower Brain - Motor Reflex Area
  • Role: subcortical.motor.flexor
  • Function: Integration of head and eye movements, controls downward vertical gaze
  • Notes to function: Projects to CN3, CN4 nuclei, rotation of body about its long axis, Project to vestibular nuclei
