Circadian rhythms are generated by the autonomous circadian clock, the suprachiasmatic
nucleus (SCN), and clock genes that are present in all tissues. The SCN times these …

The mammalian circadian system, which is comprised of multiple cellular clocks located in
the organs and tissues, orchestrates their regulation in a hierarchical manner throughout the …

In mammals, circadian rhythms of physiology and behavior are regulated by a complex
network of cellular molecular oscillators distributed throughout the brain and peripheral …

The circadian clock in mammals regulates the sleep/wake cycle and many associated
behavioral and physiological processes. The cellular clock mechanism involves a …

Circadian rhythms coordinate our physiology at a fundamental level. Over the last 20 years,
we have witnessed a paradigm shift in our perception of what the clocks driving such …

Simple Summary In mammals, circadian rhythms in nearly all behaviors and physiological
processes are controlled by the suprachiasmatic nucleus, a collection of neurons in the …

Metabolic status varies predictably on a daily and seasonal basis in order to adapt to the
cyclical environment. The hypothalamic circadian pacemaker of the suprachiasmatic nuclei …

Circadian timing affects almost all life's processes. It not only dictates when we sleep, but
also keeps every cell and tissue working under a tight temporal regimen. The daily …

24-h rhythms in physiology and behaviour are organized by a body-wide network of
endogenous circadian clocks. In mammals, a central pacemaker in the hypothalamic …

The circadian system is a key integrator of behavior and metabolism that synchronizes
physiological processes with the rotation of the Earth on its axis. In mammals, the clock is …
