The factors that govern the timing and duration of sleep and wakefulness continue to be a focal point of vigorous research within the scientific community. Nearly four decades ago, the two-process ...

In a paper published in npj Biological Timing and Sleep, researchers analyzed the mathematical structure of the two-process model (2PM) of sleep regulation, which was first proposed in the 1980s. The ...

Wonder why babies nap on some days but not on others? Or why older people wake up earlier? Mathematical modelling of sleep regulation provides some surprising answers to these and other questions, ...
