Are physiological oscillationsphysiological?

open access: yesThe Journal of Physiology, 2023
AbstractDespite widespread and striking examples of physiological oscillations, their functional role is often unclear. Even glycolysis, the paradigm example of oscillatory biochemistry, has seen questions about its oscillatory function. Here, we take a systems approach to argue that oscillations play critical physiological roles, such as enabling ...
