@@Home -> BiologicalLifeResearch -> BrainAreaFEC -> BrainRegionFEC_HT_TG_RMTG

This page covers biological details of component Rostromedial Tegmental Nucleus. Region is part of aHuman target integrated biological model.

• Top-down path to region: Hindbrain Metencephalon -> Pontine Tegmental Nuclei (HT.TG) -> Rostromedial Tegmental Nucleus (FEC.HT.TG.RMTG) (see Mind Maps)
• Type: nucleus
• Brain area: Forebrain - Execution Control Area
• Role: processor.automatic
• Function: locomotion - walking, running
• Notes to function: VTA tail
