Surrey's research team used math to show how the 2PM reflects what happens in the brain as people switch between sleep and wakefulness. They showed that the 2PM helps explain why babies at some ...

“This work shows how math can bring clarity to something as complex and personal as sleep,” Derk-Jan Dijk, co-author of the study and director of the Surrey Sleep Research Center at the University of ...

Using mathematics, the researchers were able to show that the 2PM plus light model behaves like a system of nonlinear oscillators—a sleep-wake oscillator, the oscillations of the body clock and the ...
