Waking and Sleeping following Water Deprivation in the Rat
Figure 3
Comparison of the time course of changes in behavioral parameters on the first day of recovery with comparison to the baseline.
Values (means ± S.E.M.) of different parameters are shown for each 2 h intervals of the L (09.00–21.00) and D (21.00–09.00) periods of the recovery (R1, filled circles) and base line (BL, empty circles): MA, motor activity; Thy, hypothalamic temperature. Values concerning sleep stages (Wake, NREM sleep (NREMS), REM sleep in the form of single (single REMS) and sequential (sequential REMS) episodes), the ratio of REMS to total sleep, levels of power density in the delta (0.75–4.0 Hz; band of the EEG during NREMS (NREMS-Delta)) are expressed as the percent fraction of each of the respective 2 h interval. Statistically significant comparisons are shown: treatment vs. BL (*, P<0.05).
