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

  • Top-down path to region: Forebrain Diencephalon -> Hypothalamus (FD.HT) -> Lateral Hypothalamic Area (LAC.FD.HT.LT) -> Lateral Tuberal Nuclei (LAC.FD.HT.LTUB) -> Premammillary Nucleus (LAC.FD.HT.PRM) (see Mind Maps)
  • Type: nucleus
  • Quality: L0
  • Brain area: Lower Brain - Autonomous Control Area (LAC)
  • Area circuit: Memory Autonomic Control (LAMM)
  • Role: processor.autonomic
  • Function: expression of fear responses to environmental threats
  • Notes to function:
    • integrate information involved in spatial working memory, which may result in attentional mechanisms on selection of appropriate escape strategies
