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
• Quality: L0
• Brain area: Lower Brain - Motor Reflex Area (LRC)
• Area circuit: Multisensory Orienting Reflexes (LRM)
• 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
