Fig. 8. Ablating long hairs on the postcubitus (in trailing edge regions 1–4) had a significant effect on the likelihood of eliciting a scratch when stimulating any of the regions 1–9. (A) Following ablation the probability of eliciting a scratch declined for the trailing edge regions 1–4, but increased for the wingtip region 5. (B) Following ablation the probability of eliciting a scratch increased for leading edge regions 6–9. (C). Wing regions are indicated with coloured numerals, and the claval furrow is indicated by a dashed line. The vannal region of the wing above the claval furrow is normally folded across the dorsal surface of the body, but is shown here flattened out. Dotted arrows indicate corresponding wing regions in both histograms. Boxes indicate the interquartile range, containing 50% of values, whiskers indicate the range, and horizontal lines within boxes indicate the median. Where there was no variability, only the median is shown as a horizontal line.
