Figure 8

The distribution of dopaminergic neurons and axons in the CNS of H. duryi. Filled circles indicate neurons that showed green fluorescence after glyoxylic acid treatment but were not immunostained after anti-TH IgG treatment. Gray circles were both green fluorescent after glyoxylic acid treatment and TH-IR. The axons shown are those probed with anti-TH IgG. a: dorsal surface, b: ventral surface. Anterior is up. The structures shown are BG-buccal ganglia, CG-cerebral ganglia (L-left, R-right), DB-dorsal bodies, Pd-pedal ganglia (L-left, R-right), Pl-pleural ganglia (L-left, R-right), Pr-parietal ganglia (L-left, R-right), V-visceral ganglion. ao – aorta, an – anal nerve, fn – frontolateral nerve, in – intestinal nerve, lprn – left parietal nerve, mln – median lip nerve, pen – penis nerve, rprn – right parietal nerve, tn – tentacular nerve.
