Superficial Superior Colliculus
@@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
- 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
