prr12 co-orthologs cover distinct domains of 48 hpf central nervous system. WISH evaluation of prr12 expression at 48 hpf. Scale bars: 500 µm. (A,D) lateral and (B,E) dorsal views of hybridized embryos. (A’,D’,B’,E’) represent the enlargements of the heads of the embryos shown in (A,D,B,E), respectively. (C,F) are the same embryos shown in (B’,E’), respectively, slightly tilted on a side and analyzed at higher magnifications to better show the hybridization signal in the eye. Abbreviations: DT: dorsal thalamus; H: hypothalamus; MO: medulla oblongata; P: pallium; PTd: dorsal part of posterior tuberculum; PTv: ventral part of posterior tuberculum; T: mesencephalic tegmentum; VT: ventral thalamus.
