Scientists have identified a protein in the visual system of mice that appears to be key for stabilizing the body's circadian rhythms by buffering the brain's response to light. The finding advances ...

Scientists at the Johns Hopkins University School of Medicine and the National Institutes of Health have identified a protein in the visual system of mice that appears to be key for stabilizing the ...

Within the hypothalamus, dual structures called the suprachiasmatic nuclei (SCN) act as a central clock for the circadian system, setting daily rhythms that in mature individuals are largely ...

Figure 9. (A) Diurnal rhythm control under homeostatic conditions. Initial circadian input occurs via light activating specialized retinal ganglion cells that project directly to the suprachiasmatic ...

All humans are synchronised to the rhythmic light-dark changes that occur on a daily basis. Rhythms in physiological and biochemical processes and behavioural patterns persist in the absence of all ...

Researchers report (“Daily electrical activity in the master circadian clock of a diurnal mammal”) in eLife the first-ever recording and modeling of the electrical activity of circadian clock neurons ...

You likely know circadian rhythm as the unseen hand that shakes you awake each morning and the unheard lullaby that sings you to sleep each night. But did you know this internal force affects far more ...

Are you a night owl or an early morning lark? If your preference is for getting up bright and early and getting started as soon as your feet hit the floor, then you would be considered a lark. Owls, ...
