Relation of Sleep Onset to Rapid Eye Movement Sleep
TLDR
Most investigators conceptualize rapid eye movement (REM) sleep as one of two distinct kinds of sleep, but a body of opinion persists which holds that the REM sleep cycle may be part of a more general rhythm continuing during both waking and sleeping.Abstract:
ALTHOUGH most investigators conceptualize rapid eye movement (REM) sleep as one of two distinct kinds of sleep, 1,2 a body of opinion persists which holds that the REM sleep cycle may be part of a more general rhythm continuing during both waking and sleeping. 3-10 Kleitman has discussed a "basic rest-activity cycle," reflected in the two alternating kinds of sleep, which may also be operative during waking. 3,4 Globus has reported data on daytime naps which suggests that REM sleep tends to occur at the same clock times each day 5,6 and Globus and Gardner have conceptualized REM "sleep" as a time-locked ultradian rhythm superimposed as a ripple on the slower moving circadian rhythm of waking and sleeping. 7 Similarly, Friedman and Fisher have suggested that "the concept of a sleep dream cycle be amended to that of a 24 hour continuous cycle of drive accumularead more

TL;DR: It appears that heart-rate variability may reflect the functional state of the central nervous system, even when intracranial pressure has been restored to normal.

Sleep cycle content and sleep cycle duration.
TL;DR: The results demonstrate that whereas there may be an average cycle duration of about 90 min individual cycles are very variable, the contents of a cycle influence its duration, and the onset of the REM period is not a strictly time-locked phenomenon.

Are the Eye Movements of Dreaming Sleep Related to the Visual Images of the Dreams
TL;DR: The nervous system executes a patterned output of oculomotor activity during dreaming sleep which is fairly consistent in all subjects, and it was discovered that most eye movements during REM sleep are unrelated to the action in the dream.

Sleep and Time Zone Changes: A Study in Acute Sleep Reversal
TL;DR: No definite evidence of circadian effects due to alteration in time zone were demonstrated, but early morning waking was a feature of the first five nights in the new time zone, particularly in the older subjects.

Cyclic variations in EEG during sleep and their relation to eye movements, body motility, and dreaming.
TL;DR: Records from a large number of nights in single individuals indicated that some could maintain a very striking regularity in their sleep pattern from night to night, and that body movement, after rising to a peak, dropped sharply at the onset of rapid eye movements and rebounded abruptly as the eye movements ceased.
