Cytoarchitectonic organisation of the habenulae in teleosts.(A) Drawings of adult male individuals belonging to different teleost species, placed in the context of a cladogram of the teleost lineage according to Nelson [28]. (B) Schematic representation of a teleost brain (e.g. D rerio), showing the location and orientation of histological sections shown in C–I. (C–I) Photomicrographs of cresyl-violet stained 10 µm-thick coronal sections taken at a midpoint between rostral and caudal ends of the Hb as shown in B. Each panel corresponds to a single species, as indicated in the letter code of the left diagram. C′ is a magnification of the square region depicted in C. Dorsal is to the top, and left is to the left. Arrowheads point to the subhabenular sulcus. Asterisks indicate the position of the dorsal-most neuropil region of the dorsal habenulae that is surrounded by a shell of cell bodies in some species. Abbreviations: A (anterior), D (dorsal), dHb (dorsal Hb), L (left), P (posterior), R (right), TeO (Optic Tectum), V (ventral), vHb (ventral Hb). Scale bars: 50 µm.
