---

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
• Brain area: Lower Brain - Motor Reflex Area
• Role: relay
• Function: Head and eye attention to visual stimuli
• Notes to function: Receive input primarily from the visual system and show primarily visual responses
