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, ...

If you've ever wondered why your baby naps inconsistently, the answer may lie not in parenting guides or alarm clocks—but in mathematics. A new study by researchers from the University of Surrey, ...

Contrary to common belief, not all vertebrates regulate their sleep-wake rhythm in the same way. University of Basel researchers have discovered that some fish – unlike humans – do not need orexin to ...
