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 system of mammals is composed of a hierarchy of oscillators that function at
the cellular, tissue, and systems levels. A common molecular mechanism underlies the cell …

Although circadian rhythms in mammalian physiology and behavior are dependent upon a
biological clock in the suprachiasmatic nuclei (SCN) of the hypothalamus, the molecular …

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 prominent circadian rhythms of the endocrine system are important for our broader
understanding of physiology and behavior, in both health and disease. There is now much …

In mammals, the suprachiasmatic nuclei (SCN) of the hypothalamus act as a dominant
circadian pacemaker, coordinating rhythms throughout the body and regulating daily and …

The circadian clock is an endogenous, time-tracking system that directs multiple metabolic
and physiological functions required for homeostasis. The master or central clock located …

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 nearly ubiquitous expression of endogenous 24 h oscillations known as circadian
rhythms regulate the timing of physiological functions in the body. These intrinsic rhythms …

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 …
