TLDR
It is hypothesize that persistent wakefulness of adequately long duration prior to the onset of sleep is necessary for such differential distribution in dogs as well as in man.About:

Sleep deprivation: Effect on sleep stages and EEG power density in man
TL;DR: The present findings support the hypothesis that the EEG power density in the low frequency range is an indicator of a progressively declining process during sleep whose initial value is determined by the duration of prior waking.

Sleep-deprivation: Effects on sleep and EEG in the rat
TL;DR: It is proposed that due to the existence of an intensity dimension, NREM-sleep is finely regulated around its baseline level, and thus may be readily and accurately adjusted to current ‘needs’, whereas REM-sleep, lacking an apparent intensity gradient, is regulated around a level which is considerably below baseline.

Effects of method, duration, and sleep stage on rebounds from sleep deprivation in the rat
TL;DR: Reexamination of published evidence relevant to "sleep intensity," including "negative rebounds," rebounds in other species, the effects of stress and fatigue, depth of sleep indicators, and extended sleep points out pitfalls in the designation of any specific pattern as intense sleep.

Ultradian circa 11/2 hour rhythms: a multioscillatory system.
TL;DR: These findings confirm that part of Kleitman's Basic Rest-Activity (BRAC) hypothesis which predicted about 1 1 2 hour cycles in waking levels of arousal, and suggest that ultradian 90–100 min rhythms are generated by a multi-oscillatory system.

Effects of Sleep Deprivation on Behaviour, Subsequent Sleep, and Dreaming
Ralph J. Berger,Ian Oswald +1 more
TL;DR: The EEG and eye-movements during nocturnal sleep were recorded from six males on four base-line nights and four recovery nights following 108 hours of sleep deprivation andHallucinations, paranoid delusions and other abnormal behaviour during sleep deprivation are described.

TL;DR: Compared sleep patterns prior to and following prolonged total sleep deprivation in 4 subjects, the percentages of Stage 4 and the rapid‐eye‐movement stage of sleep were increased while the percentage of Stage 2 sleep was decreased on all 3 recovery nights.

Sleep stage patterns associated with acute shifts in the sleep-wakefulness cycle.

TL;DR: The results indicate that both the quantity and cyclic period of REM sleep exhibit a circadian rhythm, whereas the propensity for stage 4 is primarily determined by prior length of time awake.
