@@Home -> BiologicalLifeResearch -> BrainAreaLRC -> BrainRegionLRC_MM_RP_RIP
This page covers biological details of component Raphe Interpositus Nucleus. Region is part of aHuman target integrated biological model.
- Top-down path to region: Midbrain Mesencephalon -> Mesencephalic Reticular Formation (MM.RF) -> Mesencephalic Reticular Formation, Midline Column (MM.RF.MID) -> Raphe Interpositus Nucleus (LRC.MM.RP.RIP) (see Mind Maps)
- Type: nucleus
- Quality: L0
- Brain area: Lower Brain - Motor Reflex Area (LRC)
- Area circuit: Frontal Visual Reflexes (LRF)
- Role: processor.automatic
- Function: Premotor network for saccades
- Notes to function:
- Gate activity of burst neurons for vertical and horizontal saccades
- omnipause neurons, part of PPRF
