“…It is also worth mentioning that during the 2 h of the recovery period, 49.68% more REM sleep accounts for only 64.95% of REM sleep recovery from their REM sleep loss during the preceding two-hour REM sleep deprivation period. Compared to our 64.95% recovery after 2 h of partial REM sleep deprivation, longer periods of REM sleep deprivation studies have shown that this recovery could be more than 70% of lost REM sleep (Dement et al, 1966;Parmeggiani et al, 1980;Stickgold et al, 1993;Rechtschaffen et al, 1999;Franken, 2002). In summary, the results of this study demonstrated that during selective REM sleep deprivation the number of attempts to enter REM sleep increased, and during the recovery period the total amount of REM sleep increased to compensate for REM sleep deficits from the preceding selective deprivation period.…”

“…Indeed, the occurrence of REM sleep rebound following total sleep deprivation or selective REM sleep deprivation is one of the most common phenomena (Dement, 1960;Vimont-Vicary et al, 1966;Morden et al, 1967;Beersma et al, 1990;Brunner et al, 1990;Endo et al, 1997Endo et al, , 1998Datta et al, 2004). More specifically, some studies have shown that the increase in REM sleep during recovery was proportional to the amount of REM sleep lost in deprivation (Dement et al, 1966;Kitahama and Valatx, 1980;Parmeggiani et al, 1980;Perez et al, 1992;Amici et al, 1994). Finally, some selective REM sleep deprivation studies have shown that during deprivation there are progressively more frequent attempts at transitions into REM sleep, an indication of a strong homeostatic drive for REM sleep (Endo et al, 1997(Endo et al, , 1998Ocampo-Garces et al, 2000;Werth et al, 2002;Datta et al, 2004).…”

The aim of this study was to elucidate physiological processes that are involved in the homeostatic regulation of REM sleep. Adult rats were chronically instrumented with sleep-wake recording electrodes. Following post-surgical recovery, rats were habituated extensively for freely moving polygraphic recording conditions. On the first experimental recording day (baseline day, BLD), polygraphic signs of undisturbed sleep-wake activities were recorded for 4 h (between 11:00 AM and 3:00 PM). During the second experimental recording day (REM sleep deprivation day, RDD), rats were selectively deprived of REM sleep for the first 2 h and then allowed to have normal sleepwake for the following 2 h. The results demonstrated that during the first 2 h, compared to BLD, RDD recordings exhibited 87.80% less time in REM sleep and 16% more time in non-REM (NREM) sleep. The total percentages of wakefulness remained comparable between the BLD and RDD. During the RDD, the mean number of REM sleep episodes was much higher than in the BLD, indicating increased REM sleep drive. Electroencephalographic (EEG) power spectral analysis revealed that selective REM sleep deprivation increased delta power but decreased theta power during the residual REM sleep. During the last 2 h, after REM sleep deprivation, rats spent 51% more time in REM sleep compared to the BLD. Also during this period, the number of REM sleep episodes with the shortest (5-30 s) and longest (>120 s) duration increased during the RDD. These findings suggest that the REM sleep homeostatic process involves increased delta-and decreased thetafrequency wave activities in the cortical EEG.

“…This condition is known to constitute an osmotic challenge leading to the progressive engagement of the whole set of mechanisms maintaining body fluid homeostasis [8], [9]. Moreover, since a REMS rebound was observed during the recovery (R) period following cold exposure [5], [6], [10], [11], [12], [13], W-S assessment was continued for two days after water was once again made freely available. Basically, two sets of parameters were assessed: i) those concerning the maintenance of osmotic homeostasis (water and food consumption; changes in body weight and fluid composition); ii) those concerning the effects of the osmotic challenge on behavioral states (hypothalamic temperature, motor activity, and W-S states).…”

Wake-sleep (W-S) states are affected by thermoregulation. In particular, REM sleep (REMS) is reduced in homeotherms under a thermal load, due to an impairment of hypothalamic regulation of body temperature. The aim of this work was to assess whether osmoregulation, which is regulated at a hypothalamic level, but, unlike thermoregulation, is maintained across the different W-S states, could influence W-S occurrence. Sprague-Dawley rats, kept at an ambient temperature of 24°C and under a 12 h∶12 h light-dark cycle, were exposed to a prolonged osmotic challenge of three days of water deprivation (WD) and two days of recovery in which free access to water was restored. Two sets of parameters were determined in order to assess: i) the maintenance of osmotic homeostasis (water and food consumption; changes in body weight and fluid composition); ii) the effects of the osmotic challenge on behavioral states (hypothalamic temperature (Thy), motor activity, and W-S states). The first set of parameters changed in WD as expected and control levels were restored on the second day of recovery, with the exception of urinary Ca++ that almost disappeared in WD, and increased to a high level in recovery. As far as the second set is concerned, WD was characterized by the maintenance of the daily oscillation of Thy and by a decrease in activity during the dark periods. Changes in W-S states were small and mainly confined to the dark period: i) REMS slightly decreased at the end of WD and increased in recovery; ii) non-REM sleep (NREMS) increased in both WD and recovery, but EEG delta power, a sign of NREMS intensity, decreased in WD and increased in recovery. Our data suggest that osmoregulation interferes with the regulation of W-S states to a much lesser extent than thermoregulation.

“…Cooling increases waking time [19], and warming promotes both NREM and REM sleep [12,19,[22][23][24][25][26]. At this point, it is sufficient to note that the thermoregulatory activity elicited by cooling is opposite of the thermolytic adjustments induced by NREM sleep processes.…”

“…Sleep time declines above and below such range but the rate of decline is larger above it than below. Deviations of ambient temperature from thermoneutrality not only increase the waking time but also modify the structure of sleep [14,15,17,[19][20][21][22]. In particular, NREM sleep stages and/or REM sleep episodes may be selectively affected.…”
