Arcuate Nucleus of Hypothalamus

@@Home -> BiologicalLifeResearch -> BrainAreaLAC -> BrainRegionLAC_FD_HT_AR

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

Top-down path to region: Forebrain Diencephalon -> Hypothalamus (FD.HT) -> Anterior Hypothalamus Area (LAC.FD.HT.AHT) -> Tuberal Area (LAC.FD.HT.TUB) -> Arcuate Nucleus of Hypothalamus (LAC.FD.HT.AR) (see Mind Maps)
Type: nucleus
Brain area: Lower Brain - Autonomous Control Area
Role: processor.autonomic
Function: Regulation of growth, appetite and body weight
Notes to function: lateral of tuberlulum, TIDA - releases dopamine to regulate secretion of prolactin hormone, GHRH - stimulate growth hormone secretion (ventrolateral)
