----

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 -> [BrainCenterMM_REF Reflexes Nuclei of Midbrain Mesencephalon] (MM.REF) -> Visual Reflexes Nuclei of Midbrain Mesencephalon (MM.REF.VIS) -> Pretectum (MM.PT) -> [BrainRegionLRC_MM_PT_PON Pretectal Olivary Nucleus] (LRC.MM.PT.PON) (see [OverallMindMaps Mind Maps])
  * *Type*: nucleus
  * *Quality*: L0
  * *Brain area*: [BrainAreaLRC 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
