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 (HTA.FD.HT) -> Lateral Hypothalamic Area (HTA.FD.HT.LT) -> Lateral Tuberal Nuclei (HTA.FD.HT.LTUB) -> Premammillary Nucleus (LAC.FD.HT.PRM) (see Mind Maps)
• *Type*: nucleus
• *Brain area*: Lower Brain - Autonomous Control Area
• *Role*: relay
• *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
