Deep Superior Colliculus
@@Home -> BiologicalLifeResearch -> BrainAreaLRC -> BrainRegionLRC_MM_SC_DEEP
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
