The epithalamic system and L-R asymmetric neural projection in zebrafish. The habenula of zebrafish is divided into a dorsal component and a ventral component (Vhb), with the dorsal habenula being constituted by the lateral (Lhb) and medial (Mhb) subnuclei of unequal size. Further components of the zebrafish epithalamus are the photosensitive pineal (Po) and the asymmetrically organized parapineal organ (Pp). The Lhb and Mhb project to the mesencephalon. The olfactory bulb (Ob) projects to the Lhb and Mhb on the right side. Bilaterally symmetric neural projections are not shown.
