Mechanisms of Circadian Oscillations

Homeostasis, which refers to the ability of organisms to maintain variables within feasible bounds despite an individual’s lifestyle and environment, is a key aspect of physiology. However, when a variable is consistently observed over a 24-h period in individuals who follow a normal daily routine (eating and being active during the day, sleeping at night), circadian patterns emerge. While the specific characteristics of these rhythms may differ on a daily basis, the overall pattern remains consistent among both individuals and among individuals.
