Electrophysiological measurements of the medial giant fiber (MGF) conduction velocity in the control and CL-20-treated worms at Day 6 and Day 13. Results are shown as mean (column) + standard error (error bar). Sample numbers are as follows: 18 (Day 6 control), 17 (Day 6 treated), 9 (Day 13 control), and 7 (Day 13 treated). Nine worms from the control and the treated groups were sacrificed immediately after the Day 6 measurement and two treated worms died leaving 7 treated worms alive at Day 13. Different letters (“A” and “B”) in the columns indicate statistically significant difference among the four groups (ANOVA, p < 0.001).
