Discovered in the 1970s, circadian clocks are essential for the regulation of biological time in most cells in the human body. These internal mechanisms adjust biological processes to a 24-hour cycle, ...

New research suggests that the suprachiasmaticus nucleus clock isn't necessary to align circadian rhythms with the light-dark cycle Circadian clocks regulate functions ranging from alertness and ...

Daily rhythms in biochemical, cellular and behavioural activities are controlled by the biological clock, which consists of one or more endogenous oscillators. The clock exerts its effects on a wide ...

New research further adds to our understanding of the circadian rhythm by suggesting that the suprachiasmaticus nucleus clock, a tiny region of the hypothalamus considered to be the body's 'master' ...
