Researchers examined a subset of GABA neurons in the circadian rhythm control center within the hypothalamus of the brain. They eliminated GABA signaling of vasopressin-producing neurons only in mice ...

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 ...

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 ...

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 ...

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, ...
