The interaction of homeostatic and circadian processes in the regulation of waking neurobehavioral functions and sleep was studied in six healthy young subjects. Subjects were scheduled to 15-24 repetitions of a 20-h rest/activity cycle, resulting in desynchrony between the sleep-wake cycle and the circadian rhythms of body temperature and melatonin. The circadian components of cognitive throughput, short-term memory, alertness, psychomotor vigilance, and sleep disruption were at peak levels…

Sleep and Wakefulness Out of Phase with Internal Biological Time Impairs Learning in Humans
TLDR
The results establish that proper alignment between sleepwakefulness and internal circadian time is crucial for enhancement of cognitive performance and demonstrate that exposure to dim light is sufficient to expand the range of entrainment in humans.
Melatonin advances the circadian timing of EEG sleep and directly facilitates sleep without altering its duration in extended sleep opportunities in humans
TLDR
Robust, direct sleep‐facilitating and circadian effects of melatonin are demonstrated without concomitant changes in sleep duration, and support the use ofmelatonin in the treatment of sleep disorders in which the circadian melatonin rhythm is delayed relative to desired sleep time.
Amplitude Reduction and Phase Shifts of Melatonin, Cortisol and Other Circadian Rhythms after a Gradual Advance of Sleep and Light Exposure in Humans
Background The phase and amplitude of rhythms in physiology and behavior are generated by circadian oscillators and entrained to the 24-h day by exposure to the light-dark cycle and feedback from the
Intrinsic Period and Light Intensity Determine the Phase Relationship between Melatonin and Sleep in Humans
TLDR
It is demonstrated that neurobiological and environmental factors interact to regulate the phase angle of entrainment in humans and has important implications for understanding physiological organization by the brain’s master circadian clock and may have implications forUnderstanding mechanisms underlying circadian sleep disorders.
CONTRIBUTION OF CIRCADIAN PHYSIOLOGY AND SLEEP HOMEOSTASIS TO AGE-RELATED CHANGES IN HUMAN SLEEP
TLDR
The internal circadian phase advance of awakening, as well as the age-related reduction in sleep consolidation, appears related to an age- related reduction in the promotion of sleep by the circadian pacemaker during the biological night in combination with a reduced homeostatic pressure for sleep.

TLDR
Taken as a whole, this accumulation of sleep pressure during wakefulness and its abatement during sleep can be thought of as an active maintenance of a balance state, or a homeostasis, as one may think of hunger or osmolarity.
CONTRIBUTION OF CORE BODY TEMPERATURE, PRIOR WAKE TIME, AND SLEEP STAGES TO COGNITIVE THROUGHPUT PERFORMANCE DURING FORCED DESYNCHRONY
TLDR
The results demonstrate that variations in core body temperature, time awake, and amount of REM sleep are associated with changes in cognitive throughput performance, and suggest that cognitive throughput may be more sensitive to variations in REM sleep than SWS.

TLDR
A potent circadian cycle in the drive for wakefulness, which is generated by the suprachiasmatic nucleus is revealed, which reaches a peak during the evening hours just before habitual bedtime.
CIRCADIAN RHYTHMS OF PSYCHOMOTOR VIGILANCE, MOOD, AND SLEEPINESS IN THE ULTRA-SHORT SLEEP/WAKE PROTOCOL
TLDR
Most mood subscales exhibited significant deterioration in day 2 of the protocol without alteration of circadian pattern, however, neither sleepiness nor performance was worse on the second day of observation compared to the first day, providing further support for the use of the ultra-short sleep/wake protocol for measurement of circadian rhythms.

Circadian and sleep/wake dependent aspects of subjective alertness and cognitive performance
TLDR
It was revealed that prior wakefulness within a range of 0–18 h significantly reduced alertness and performance and that the circadian rhythm of core body temperature paralleled the circadian Rhythm of alerts and performance.
Circadian pacemaker interferes with sleep onset at specific times each day: role in insomnia.
TLDR
The temporal isolation data account quantitatively for the timing of the afternoon siesta and suggest that malfunctions of the phasing of the circadian pacemaker may underlie the insomnia associated with sleep-scheduling disorders.

TLDR
Analyses of the (nonadditive) interaction of the circadian and sleep-dependent components of sleep propensity and sleep structure revealed that the phase relation between the sleep-wake cycle and the circadian pacemaker during entrainment promotes the consolidation of sleep and wakefulness and facilitates the transitions between these vigilance states.
Ageing and the circadian and homeostatic regulation of human sleep during forced desynchrony of rest, melatonin and temperature rhythms
TLDR
Age‐related decrements in sleep consolidation and increased susceptibility to circadian phase misalignment in older people appear to be related to the interaction between a reduction in the homeostatic drive for sleep and a reduced strength of the circadian signal promoting sleep in the early morning.
Timing of REM sleep is coupled to the circadian rhythm of body temperature in man.
TLDR
There is an endogenous circadian rhythm of REM sleep propensity which is closely coupled to the body temperature rhythm and is capable of free-running with a period different from both 24 hr and the average period of the sleep-wake cycle.
Effects of a prolonged 3-hour sleep-wake cycle on sleep stages, plasma cortisol, growth hormone and body temperature in man.
TLDR
Despite significant sleep deprivation, a circadian pattern of total sleep time persisted throughout the 10-day ultradian condition and the distribution and amount of REM sleep time was most affected with stages 3–4 sleep least affected.
Nocturnal melatonin onset is phase locked to the primary sleep gate.
TLDR
Melatonin participates in sleep-wake regulation in humans and there was an inverse relationship between melatonin and core body temperature and an almost perfect out-of-phase relationship between sleep propensity and temperature.
Sleep Initiation and Initial Sleep Intensity: Interactions of Homeostatic and Circadian Mechanisms
TLDR
The present model is able to simulate the time course of PSI under baseline conditions as well as following recovery sleep after extended sleep deprivation and suggests that during the regular period of waking, a circadian process teracts the increasing sleep propensity induced by a homeostatic process.
Timing of human sleep: recovery process gated by a circadian pacemaker.
TLDR
The model shows that the experimental data are consistent with the concept of a single circadian pacemaker in humans, which has implications for the understanding of sleep as a restorative process and its timing with respect to day and night.
Variation of electroencephalographic activity during non‐rapid eye movement and rapid eye movement sleep with phase of circadian melatonin rhythm in humans
TLDR
Data indicate that the circadian pacemaker induces changes in EEG activity during REM and non‐REM sleep, which are dissimilar from the spectral changes induced by sleep deprivation and exhibit a close temporal association with the melatonin rhythm and the endogenous circadian phase of sleep consolidation.
