This page covers biological details of component Pretectal Olivary 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) -> Pretectum (MM.PT) -> Pretectal Olivary Nucleus (LRC.MM.PT.PON) (see Mind Maps)
- Type: nucleus
- Quality: L0
- Brain area: Lower Brain - Motor Reflex Area (LRC)
- Area circuit: Direct Visual Reflexes (LRV)
- Role: processor.automatic
- Function: Pupillary light reflex and modulating subcortical nuclei involved in circadian rhythms
- Notes to function:
- Primary visual centre, involved in the pupillary light reflex, receives retinal input
