Circadian pacemaker neurons in the Drosophila brain display daily rhythms in the levels of intracellular calcium. These calcium rhythms are driven by molecular clocks and are required for normal ...

Circadian rhythms are inherent cycles of approximately 24 hours that regulate various biological processes, such as sleep and wakefulness. A research group at Nagoya University in Japan has recently ...

Everyone knows morning people and late-night owls. The variation in individual circadian rhythms is an anecdotal as well as experimentally verified fact. But, until now, to systematically study ...

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 is ...

This sidebar to “Tossing and Turning: Treatment and Side Effects Disrupt Sleep” discusses the physiology of sleep, REM sleep, circadian rhythms, and sleep research. “One of the misconceptions of sleep ...

Circadian rhythms are endogenous oscillations widely present in living organisms, typically following approximately 24-hour ...
