Fig. 4 Expression of nlgns in the developing brain at 48 hpf. The expression patterns for the nlgn genes (A-G) were examined by ISH in cross-sections of embryos at 48 hpf. The levels of the sections (1-5) correspond to sections 2, 3, 5, 8, and 12, respectively, in the ZFIN atlas of zebrafish anatomy (zfin. org/zf_info/anatomy/48hrs/48hrs.html). d, diencephalon; e, eye; m, midbrain; h, hindbrain; ht, hypothalamus; hy, hypophysis; op, olfactory placode; ot, optic tectum; ov, otic vesicle; pfb, pectoral fin bud. Scale bar = 105 μm in A1-G4 and 100 μm in A5-G5.
