It is beyond doubt that the timing of sleep is under control of the circadian pacemaker. Humans are a diurnal species; they sleep mostly at night, and they do so at approximately 24-h intervals. If they do not adhere to this general pattern, for instance when working night shifts or when travelling across time zones, they experience the stubborn influence of their circadian clock. In recent years much has been discovered about the organisation of the circadian clock. New photoreceptor cells in… Expand
Daily rhythms of the sleep-wake cycle
TLDR
Current work aims to identify the detailed nature of processes S and C, which combine approximately additively to determine the times of sleep onset and waking. Expand
Cognition in circadian rhythm sleep disorders.
TLDR
The influence of circadian modulation of alertness and cognitive function is evident even when the pressure for sleep is high, which means that circadian misalignment is the basis for all circadian rhythm sleep disorders. Expand
The developmental emergence of a wake-promoting pathway regulating ultradian and circadian rhythms in infant rats
In mammals, circadian rhythms are controlled by an endogenous clock located in the suprachiasmatic nucleus (SCN). The SCN is part of a wake-promoting pathway in adults involving the dorsomedialExpand
The periodicity of sleep duration – an infradian rhythm in spontaneous living
TLDR
The nature of the observed oscillations in total sleep time in healthy adults under spontaneous living conditions is explored to provide a better understanding of sleep need in short versus long sleepers, in predicting work performance, and reducing sleepiness-related accidents following shift work.

HIPPOCAMPAL CIRCADIAN RHYTHMS IN TEMPORAL LOBE EPILEPSY
For over a century epileptic seizures have been known to cluster at specific times of the day. Recent studies have suggested that the circadian regulatory system may become permanently altered inExpand
How is the inner circadian clock controlled by interactive clock proteins?
TLDR
This review defines circadian clocks, their composition and underlying molecular mechanisms, and describes and discusses recent crystal structures of Drosophila and mammalian core clock components and the enormous impact they had on the understanding of circadian clock mechanisms. Expand
Circadian rhythm sleep disorders
TLDR
This review will focus on etiological underpinnings, clinical assessments, and evidence-based treatment options for circadian rhythm sleep disorders, and the expected prevalence of each condition within general medical practice. Expand
Sleep in birds: lying on the continuum of activity and rest
TLDR
The present review focuses on some of above mentioned facts about sleep in higher vertebrates particularly in birds, as it lies on the continuum of activity and rest. Expand
Modulation of Motoneuronal Activity With Sleep-Wake States and Motoneuronal Gene Expression Vary With Circadian Rest-Activity Cycle
In both nocturnal and diurnal mammals, sleep and wake states differentially aggregate during the rest and active phases of circadian cycle. Closely associated with this rhythm are prominent changesExpand
Environmental chemicals affect circadian rhythms: An underexplored effect influencing health and fitness in animals and humans.

TLDR
The behavioral and neurobiological evidence suggests that in rodents and humans, the circadian clock actively promotes both wake and sleep, at different phases of the circadian cycle. Expand

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. Expand
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. Expand

TLDR
It is argued that animal and human circadian rhythm researchers should (continue to) use constant routines as a step on the road to getting through to central and peripheral circadian oscillators in the intact organism. Expand

TLDR
Recent findings concerning the entrainment of clock gene expression in the central nervous system and in peripheral tissues by periodic food access are presented, and the implications of these findings for a better understanding of a circadian system that entrains to meals, rather than to light, are discussed.

Timing and Consolidation of Human Sleep, Wakefulness, and Performance by a Symphony of Oscillators
TLDR
Interindividual differences in sleep timing, duration, and morning or evening preference are associated with changes of circadianor sleep homeostatic processes or both and molecular genetic correlates, including polymorphisms in clock genes, of some of these interindividual differences are emerging.

TLDR
Greater understanding of the cellular and molecular mechanisms of the SCN clockwork provides opportunities for pharmacological manipulation of circadian timing. Expand

TLDR
The daily temporal pattern of hypocretin-1 in the cisternal CSF of the squirrel monkey, a New World primate with a pattern of wake similar to that of humans, was examined, indicating a circadian-independent component to hypocretIn-1 regulation. Expand
Mammalian Cry1 and Cry2 are essential for maintenance of circadian rhythms
TLDR
It is shown that mice lacking the Cry1 or Cry2 protein display accelerated and delayed free-running periodicity of locomotor activity, respectively, which suggests that, in addition to a possible photoreceptor and antagonistic clock-adjusting function, both proteins are essential for the maintenance of circadian rhythmicity.
