Fig. 7.
Time course of EEG power density in NREM sleep.Top, Light period of baseline 2 (six 2 hr intervals;1–6). Bottom, Light period after sleep deprivation (three 2 hr intervals; 1–3) for the Prn-p+/+ and Prn-p0/0 mice. The curves connect geometric means of relative EEG power density for consecutive 2 hr intervals (n = 8 for each genotype). Values are plotted at the upper limit of each bin. The baseline data are expressed relative to the first 2 hr interval of the light period (=100%). Consecutive 2 hr intervals of recovery are expressed relative to the first three consecutive 2 hr intervals of the light period of Baseline 2 (=100%). Lines below the abscissa indicate frequency bands that differed significantly from 100% (p< 0.05, top, one-way ANOVA “2 hr intervals”;bottom, frequency bands: 0.5–4.0, 6.25–9.0, 11.25–25 Hz; two-tailed t test).
