Circadian rhythms (CR) are a series of endogenous autonomous oscillators generated by
the molecular circadian clock which acting on coordinating internal time with the external …

Mammalian circadian rhythms are controlled by endogenous biological oscillators, including
a master clock located in the hypothalamic suprachiasmatic nuclei (SCN). Since the period …

Light exerts a wide range of effects on mammalian physiology and behavior. As well as
synchronizing circadian rhythms to the external environment, light has been shown to …

The suprachiasmatic nucleus (SCN) is the primary circadian pacemaker in mammals.
Individual SCN neurons in dispersed culture can generate independent circadian …

Neurons in the suprachiasmatic nucleus (SCN) function as part of a central timing circuit that
drives daily changes in our behaviour and underlying physiology. A hallmark feature of SCN …

Circadian rhythms are essential for the survival of all organisms, enabling them to predict
daily changes in the environment and time their behaviour appropriately. The molecular …

In mammals, including humans, nearly all physiological processes are subject to daily
oscillations that are governed by a circadian timing system with a complex hierarchical …

Organisms have developed concurrent behavioral and physiological adaptations to the
strong influence of day/night cycles, as well as to unforeseen, random stress stimuli. These …

The circadian system actively synchronizes the temporal sequence of biological functions
with the environment. The oscillatory behavior of the system ensures that entrainment is not …

Cortisol has one of the most distinct and fascinating circadian rhythms in human physiology.
This is regulated by the central clock located in the suprachiasmatic nucleus of the …
