Expression of neurotransmitter-related genes. a–l Lv-vacht is expressed beginning in some embryos at 22 hpf in the postoral neurons (arrowhead in g) where it remains through 32 hpf. m–x Lv-drd1 is expressed starting at 24 hpf in the ectoderm near the stomodeum and near the postoral neurons (arrowheads in t), where it remains through 32 hpf. a′–l′ Lv-asicl4 is expressed beginning at 24 hpf in the developing apical organ (arrowhead in h′) through 32 hpf. Scale bars = 50 μm
