Habenula anatomy and connections. (A) The human habenula illustrated in orthogonal slices using the MNI template brain (MNI152b) (16). (B) Highlighting regions connected with the habenula (17–20) illustrated using a medial view of a high-resolution, high contrast template (21). The habenula is highlighted in purple. Areas with direct connections to the habenula are highlighted in blue; areas that are functionally associated with the habenula are highlighted in green. a, areas; Amy, amygdala; BFB, basal forebrain; BG, basal ganglia; Hc, hippocampus; Hypo, hypothalamus; IPN, interpeduncular nucleus; mPFC, medial prefrontal cortex; NBM, nucleus basalis of Meynert; PAG, periaqueductal gray; PFC, prefrontal cortex; RMT, rostromedial tegmental nucleus; RN, raphe nuclei; SN, substantia nigra; Th, thalamus; VTA, ventral tegmental area; *approximate/example position of the region.
