arid1b−/− larvae are hyper-responsive to low stimulus intensities during the night. A. Stimulus-response curves for arid1b+/+, +/−, and −/− larvae from arousal threshold assay. B. arid1b−/− larvae show significantly increased (F(2,27) = 10.10, p = 0.0005, by one-way ANOVA) responsiveness to lower intensity stimuli (<5 a.u.) compared to arid1b+/+ (p = 0.0031, by Tukey’s multiple comparisons test) and +/− (p = 0.0010, by Tukey’s multiple comparisons test). C. No significant differences were observed among groups at higher intensity stimuli (>5 a.u.). Asterisks indicate significance following p-value adjustment using Tukey’s multiple comparisons test. **p < 0.01, ***p < 0.001. Data are presented as mean ± 95% CI for group averages across each of 10 trials (n = 10 trials for 44 arid1b+/+, 94 arid1b +/−, and 45 arid1b −/− larvae).
