TLDR
It was concluded that the findings of the present experiment can be explained most parsimoniously in terms of increased sensitivity of REM-deprived subjects to environmental stimulation.Abstract:
Four experiments were performed to test the behavioral effects of REM deprivation on rats. Two studies of avoidance learning showed that shuttle avoidance and runway avoidance were unaffected by REM deprivation. REM deprivation produced an enhancement of activity, and the addition of periodic shock demonstrated a failure of adaptation for REM-deprived subjects.
These data were interpreted as indicating that REM deprivation produces motivational effects on rat behavior and that electric shock-induced pain and REM deprivation interact to change activity patterns. It was concluded that the findings of the present experiment can be explained most parsimoniously in terms of increased sensitivity of REM-deprived subjects to environmental stimulation.read more

Behavioral and anatomical correlates of chronic episodic hypoxia during sleep in the rat
TL;DR: It is concluded that EHYP is associated with marked cellular changes over time within neural regions associated with cognitive functions and may underlie components of the learning and memory impairments found in OSA.

The reinterpretation of dreams: An evolutionary hypothesis of the function of dreaming
TL;DR: In this paper, the authors put forward the hypothesis that the biological function of dreaming is to simulate threatening events, and to rehearse threat perception and threat avoidance, which is supported by empirical evidence from normative dream content, children's dreams, recurrent dreams, nightmares, post traumatic dreams, and the dreams of hunter-gatherers.
Journal ArticleDOI
A Review of REM Sleep Deprivation
TL;DR: Controlled but unconfirmed work indicates that that endogenous, but not reactive, depressive patients are improved by REM sleep deprivation, a finding consistent with the animal behavioral consequences of the procedure and with the unique REM-depriving properties of efficacious antidepressant drugs.

TL;DR: In this article, rats were deprived of paradoxical (radid eye movement or REM) sleep for a 6-day period but were allowed substantial non-REM (slow wave) sleep.

TL;DR: Negligible differences were found between 3 and 6-day deprived rats in compensation for lost REM time on recovery days, suggesting a ‘plateau’ effect.

TL;DR: The highest shock level produced significantly longer escape latencies on early trials but did not retard avoidance learning, and these results are compared with those found using other avoidance tasks.
