This page covers biological details of component Deep 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) -> Deep Superior Colliculus (LRC.MM.SC.DEEP) (see Mind Maps)
  • Type: nucleus
  • Brain area: Lower Brain - Motor Reflex Area
  • Role: subcortical.motor.flexor
  • Function: Head and eye attention to non-visual stimuli
  • Notes to function: Receive many types of input and project to numerous motor-related brain areas
