Mutation of <i>mod-5</i> suppresses the hyperactivity but not the large speed fluctuations of <i>cat-2</i> mutants.

<p>(A) Average speeds of wild-type and mutant animals tested in the well-fed on-bacteria and food-deprived on-bacteria conditions. (B) The average standard deviations of speed measurements within individual tracks for animals on a bacterial lawn. p-values for difference in average speeds were calculated using Student's T-test. p-values for differences between standard deviation curves for each genotype were calculated using two-way ANOVA. Tracks were first grouped by average speed. Error bars, SEMs. (A: wild-type n = 120 well-fed, 109 food-deprived tracks; <i>cat-2(e1112)</i> n = 123, 96; <i>mod-5(n3314)</i> n = 58, 53; <i>mod-5(n3314) cat-2(e1112)</i> n = 83, 51; B: wild-type n = 233 tracks; <i>cat-2(e1112)</i> n = 131; <i>mod-5(n3314)</i> n = 219; <i>mod-5(n3314) cat-2(e1112)</i> n = 90, all tracks >30 sec)
