Figure 1. MHb-IPN connectivity.

Figure 1

Schematic sagittal view of a mouse brain showing known MHb afferents (blue), MHb efferents (red), IPN afferents (purple) and IPN efferents (orange). The thickness of the arrows reflects the strength of the connection. 3V, third ventricle; 4V, fourth ventricle; DR, dorsal raphe; DTg, dorsal tegmental nucleus; EC, entorhinal cortex; HC, hippocampus; Hyp, hypothalamus; IPN, interpeduncular nucleus; LC, locus coeruleus; LDTg, laterodorsal tegmental nucleus; LHb, lateral habenula; LV, lateral ventricle; MHb, medial habenula; MnR, median raphe; NI, nucleus incertus; PAG, periaqueductal gray; Thal, thalamus; VTA, ventral tegmental area.
