Detailed organisation of the ventral nerve cords in Onychophora as revealed by different markers: antisera against tyramine (a), allatostatin (b), perisulfakinin (c), pigment-dispersing-factor (PDF; d) and RFamide (e). Maximum projection confocal micrographs of Euperipatoides rowelli at the level of the leg. Median is up. Cases where the distribution of somata is significantly different to uniform are indicated (χ2 *, **, ***, ****, p < 0.05, 0.01, 0.001, 0.0001 respectively; n.s. not significant; see Table 1 for more details). ln, leg nerve.
