---

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

• Top-down path to region: Forebrain Telencephalon -> Extended Amygdala (FAM.FT.EXTAM) -> Amygdala (FAM.FT.AM) -> Basolateral Nuclear Complex (FAM.FT.AM.BL) -> Lateral Amygdaloid Nucleus (FAM.FT.AM.LA) -> Ventromedial Amygdaloid Nucleus (FAM.FT.AM.LAVM) (see Mind Maps)
• Type: nucleus
• Quality: L0
• Brain area: Forebrain - Affective Motivations Area (FAM)
• Area circuit: Fast Unconditional Sensory Data and Association Memory (FAMXUS)
• Role: processor.affective
• Function: conditional and unconditional convergence to affect polymodal memory formation
• Notes to function:
  • LA3
  • projects to ET
