Effect of oral purine metabolite administration on sleep architecture. a Experimental schedule. BL, baseline EEG recording (ZT = 3–9); AL, EEG recording soon after learning (ZT = 3–9). b–e Sleep architecture during the recording periods: total amount (B), mean duration (C), and episode count (D) of each sleep–wake state and transition ratio between states (E)(control, n = 5 mice; hypoxanthine, n = 4; xanthine, n = 3; allantoin, n = 4; urea, n = 4; two-way ANOVA followed by Sidak’s multiple comparisons, control vs. urea, *p < 0.05, error bars, SEM). (F-L) Power analysis using Fast Fourier Transformation of EEG amplitude during BL (F–H) and AL (I-K) and their density (L; two-way ANOVA followed by Sidak’s multiple comparisons, p > 0.05, error bars, SEM)
