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
• Brain area: Lower Brain - Motor Reflex Area
• Role: relay
• 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
