The habenula (Hb) is a diencephalic brain region implicated in adaptive behaviors and neuropsychiatric disorders. Two main Hb subdivisions, the lateral habenula and medial habenula, have been shown to play different roles in diverse behaviors, ranging from classical and operant learning to the prediction of outcomes, fear, addiction, and social interactions. However, our understanding of cytoarchitecture and topography of the vertebrate Hb, as well as how different Hb microcircuits are organized across species, remains limited. In this study, we utilized a combination of single-cell and spatia
