Circadian rhythms play an influential role in nearly all aspects of physiology and behavior in
the vast majority of species on Earth. The biological clockwork that regulates these rhythms …

Adrenal glucocorticoids are major modulators of multiple functions, including energy
metabolism, stress responses, immunity, and cognition. The endogenous secretion of …

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 …

Anecdotally, there can be little doubt that sleep plays a role in maintaining a good mood and
cognitive acuity. Sleep deprivation one night followed by “getting a good night's sleep” on …

The brain and body need to adapt constantly to changing social and physical environments.
A key mechanism for this adaptation is the 'stress response', which is necessary and not …

The mammalian circadian clock regulates day–night fluctuations in various physiological
processes. The circadian clock consists of the central clock in the suprachiasmatic nucleus …

Glucocorticoids, hormones produced by the adrenal gland cortex, exert numerous functions
in body homeostasis and the response of the organism to external stressors. One striking …

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 is composed of coupled endogenous oscillators that allow living
beings, including humans, to anticipate and adapt to daily changes in their environment. In …

Circadian rhythms align physiological functions with the light–dark cycle through oscillatory
changes in the abundance of proteins in the clock transcriptional programme. Timely …
