Wheel-running behavior in Shank3∆C mice across 5 weeks of continuous light:dark (LD) cycles.
Summary of wheel-running behavior measured for each week of 12:12 hr light:dark cycles for both wild type and Shank3∆C mice. A linear mixed-effects ANOVA was used to estimate the contributions of genotype and the interaction between genotype and time for period, alpha, and wheel-running activity for LD week 1 through 5. There is no significant interaction effect for genotype x time for period (p=0.41), but there is a significant effect of genotype (p=0.047, indicated by *). There is no significant interaction effect for genotype x time for alpha (p=0.43), but there is a significant effect of time (p=0.004, indicated by †). There is a significant interaction effect (indicated by vertical bar) for genotype x time for activity (p<0.0001). See Source data 1 for details. Values are means ± SEM for wild type (n = 8) and Shank3∆C (n = 8) mice.
