Mean ± SEM percentage (n = 8 per genotype) recording time for W, SWS, and PS and the percentage PS/SWS for the light (L) and dark (D) periods for REC1 and REC2. Variables were affected by genotype and/or sleep deprivation (two-way ANOVA; REC1 light∶factor genotype: W, SWS, PS, p < 0.05; factor SD: W, PS, PS/SWS, p < 0.005 and SWS,p < 0.05; interaction: PS, p < 0.07; REC1 dark: factor SD: PS, PS/SWS, p < 0.001 and W,p < 0.05; REC2 light: factor SD: W, SWS, PS/SWS,p < 0.01; REC2 dark:factor SD:PS, PS/SWS,p < 0.005). p indicates the probability of the t tests comparing the genotypes.
ap < 0.005, bp < 0.05, significant difference from the second baseline day (Table 1); pairedt test.
