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
