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

• Top-down path to region: Forebrain Diencephalon -> Hypothalamus (FD.HT) -> Posterior Hypothalamic Area (LAC.FD.HT.POS) -> Posterior Hypothalamic Nucleus (LAC.FD.HT.PN) (see Mind Maps)
• Type: nucleus
• Quality: L0
• Brain area: Lower Brain - Autonomous Control Area (LAC)
• Area circuit: Vision Autonomic Control (LAV)
• Role: processor.autonomic
• Function: Blood pressure, pupillary dilation
