This page covers biological details of component Gigantocellular Reticular Nucleus. Region is part of aHuman target integrated biological model.
- Top-down path to region: Hindbrain Myelencephalon -> Medullary Reticular Formation (HL.RF) -> Medullary Reticular Formation, Medial Column (HL.RF.MED) -> Gigantocellular Reticular Nucleus (LRC.HL.PRF.GCR) (see Mind Maps)
- Type: nucleus
- Quality: L0
- Brain area: Lower Brain - Motor Reflex Area (LRC)
- Area circuit: Postural Control Reflexes (LRP)
- Role: subcortical.motor.flexor
- Function: Vasodepressor center
- Notes to function:
- Projects to hypoglossal nucleus, abducens
- medullary (lateral) reticulospinal tract
- excite trunk flexors, inhibit extensors
- stimulation induces inspiration
