Effects of 1-s darkness stimuli on locomotion. A Second-by-second average activity of the flies before and after the sudden darkness stimuli for all trials. B Delta index was calculated for each stimuli presentation trial (p = 0.011 for lines’ differences; two-way ANOVA). C Average of all trials’ delta index (CSORC × Fragile X p = 0.033; w1118 × Fragile X p = 0.015; one-way ANOVA and Holm-Sidak post hoc test). D Percentages of trials in which flies responded with a decrease, increase, or no change in movements (nCSORC = 58; nw1118 = 62; nFragile X = 58 from 4 independent experiments)
