This page covers biological details of component Darkschewitsch 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) -> Darkschewitsch Nucleus (LRC.MM.DSCH) (see Mind Maps)
  • Type: nucleus
  • Quality: L0
  • Brain area: Lower Brain - Motor Reflex Area (LRC)
  • Area circuit: Frontal Visual Reflexes (LRF)
  • Role: processor.automatic
  • Function: Mediate the consensual pupillary light reflex
  • Comments: Accessory oculomotor nucleus
  • Notes to function:
    • Light in one eye results in pupil changes in another eye
