@@Home -> BiologicalLifeResearch -> BrainAreaLRC -> BrainRegionLRC_MM_SC_INT

This page covers biological details of component Intermediate 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) -> Intermediate Superior Colliculus (LRC.MM.SC.INT) (see Mind Maps)
• *Type*: nucleus
• *Brain area*: Lower Brain - Motor Reflex Area
• *Role*: relay
• *Function*: Sensimotor integration for orienting
• *Notes to function*: Receive GABA from SNpr to gate integration
