@@Home -> BiologicalLifeResearch -> BrainAreaLRC -> BrainRegionLRC_MM_SC_SUP

This page covers biological details of component Superficial Superior Colliculus. 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) -> Superior Colliculus (MM.SC) -> Superficial Superior Colliculus (LRC.MM.SC.SUP) (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: Head and eye attention to visual stimuli
  • Notes to function:
    • Receive input primarily from the visual system and show primarily visual responses
