One of the most striking features of our world is the continuous cycle of day and night. Almost all living organisms, ...

Here we demonstrated that the circadian rhythm of SCN electrophysiological activity showed two distinct peaks when slices were cut in the horizontal plane. In horizontal slices, a morning peak ...

Increasing evidence highlights a bidirectional relationship between circadian disruption and hepatic pathophysiology, suggesting liver disease is both a consequence and a driver of circadian ...

"The SCN is considered our central clock and plays a crucial role ... For example, depending on the rhythm of the heart’s clock, the heart muscle may be particularly efficient at pumping blood during ...

These rhythms are orchestrated by the suprachiasmatic nucleus (SCN) in the hypothalamus and involve a network of genes, including CLOCK and BMAL1, that influence metabolism, immune responses ...

The 'master clock' is in the hypothalamus of your brain and helps determine the circadian rhythm. Where it's located is called the suprachiasmatic nucleus [SCN] and it sends signals to other ...

We can't talk about morning sunlight and improved sleep hygiene without first addressing our circadian rhythm. This is the body's 24-hour sleep-wake cycle. It naturally responds to light and darkness, ...

In the morning, your eyes sense the sunlight, and then the SCN triggers the release of cortisol to help wake up your body. Getting sunlight in the morning helps regulate your circadian rhythm as ...

Circadian System and Brain Function Circadian rhythms are governed by the suprachiasmatic nucleus (SCN) of the hypothalamus, which synchronizes peripheral clocks throughout the body. These rhythms ...
