mec-10 is important, but not essential, for anterior gentle touch avoidance. Animals were touched with an eyelash at the indicated positions; escape responses (reversals) were scored as described. mec-10(tm1552) and mec-10(u20) animals were significantly less responsive than wild-type at all positions (***P < 0.001) according to the Student's t-test (n = 100 for each genotype over 5 different days). One-way ANOVA demonstrated a statistically significant difference in the responses of mec-10(tm1552) and mec-10(u20) animals at different positions along the anteroposterior axis (P < 0.001).
