Thus, there is little doubt that enforced wakefulness is stressful. However, an alternative explanation has been proposed—that only a portion of sleep (“obligatory sleep”) is actually required for accomplishing the function of sleep and that the remainder (“facultative sleep”) can be lost without consequences (14). J Neurophysiol 2002; 88(2):1073–1076. 137. Indeed, nocturnal exposure to increased HPA activity has been shown to promote sleep fragmentation (58,59), and could therefore further impair sleep quality and increase the sleep debt.

Additional evidence comes from human studies (68–71), where the methods used to enforce sleep deprivation (motivational factors, social interactions, resort to demanding tasks) may be effective at avoiding substantial microsleep episodes for a longer time, consistent with the longer time constant of the buildup of slow-wave activity compared to other species (67) online.

If water depth is limited to 1 cm in the bottom of the bucket, the animal gets minimal water exposure. However, it learns to sleep stretched out over the top of the small platform such that by the fourth day REM sleep episodes of several minutes duration can be obtained. As more REM sleep is obtained, the amount of NREM sleep, especially SWS, is reduced Boys & Sex read epub
