This page covers biological details of component Medial Habenula. Region is part of aHuman target integrated biological model.

  • Top-down path to region: Forebrain Diencephalon -> Habenula (FAM.FD.HB) -> Medial Habenula (FAM.FD.MHB) (see Mind Maps)
  • Type: nucleus
  • Brain area: Forebrain - Affective Motivations Area
  • Role: processor.affective
  • Function: Encoding negative feedback, indirect
  • Notes to function: affects VTA, dorsal raphe but via interpeduncular nucleus
