Circadian rhythms are the cycles that tell the body when to sleep, wake, and eat—the biological and psychological processes that oscillate in predictable patterns each day. This internal clock ...

Circadian clocks are cell autonomous and these cellular clocks are located in SCN neurons as well as in almost every cell in the body. The molecular mechanism of circadian clocks in mammals ...

The signals appear at appropriate times, thanks to the circadian clock. Using rhythmic environmental cues such as light, the circadian clock sets up a 24-hour internal oscillation that is replicated ...

Your circadian rhythm is your body’s internal clock. Light, sleep patterns, hormones, meals, and temperature can all influence your circadian rhythm, which in turn can influence your overall health.

You’re not the only one to have them It’s thought any life form that derives energy from sunlight has some kind of circadian rhythm ... your body clock would become out of step with the ...

“The circadian rhythm is generated by the master clock in the brain, an area of 50,000 cells near the hypothalamus [the hormonal control centre of the brain],” says Dr Kat Lederle, founder of ...

In mammals, this role is also suggested by the localization of the circadian clock in the bilaterally paired suprachiasmatic nuclei (SCN) of hypothalamus. In order to investigate the possible ...

Human life is governed by a circadian rhythm (around 24 hours) that is controlled by a tiny biological clock located in the ...

Adolescence is not only a particularly vulnerable time for developing mental disorders – it’s also a time when sleep and circadian rhythms change. Adolescents often sleep later, due to a delay ...

The circadian clock plays a key role in coordinating many biological processes from behaviors to cellular metabolism and mitosis. Disruption of circadian rhythms can increase susceptibility to ...
