Waking and Sleeping following Water Deprivation in the Rat

Build-up of delta power during consolidated non-rapid eye movement sleep episodes.
Build-up of power density in the delta (0.75–4.0 Hz) band of the EEG during consolidated non-rapid eye movement sleep (NREMS) episodes (i.e. lasting more than 2 min) occurring in rats (n = 8) under normal laboratory conditions (average of two days of baseline, BL), during the third day of a water deprivation protocol (WD3) and the first day of recovery (R1) which followed the reestablishment of access to water. Values (means ± S.E.M.) are expressed as the percentage of the mean 24-h level of the BL.
