This page covers biological details of component Principal Pretectal 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) -> Principal Pretectal Nucleus (LRC.MM.PT.PR) (see Mind Maps)
  • Type: nucleus
  • Brain area: Lower Brain - Motor Reflex Area
  • Role: processor.automatic
  • Function: Pupillary light reflex
  • Notes to function: Affected by visual cortex and projects to EWN
