Abstract

The counterintuitive noise effect in nonlinear systems plays an important role in determining the system dynamics. Circadian rhythm is an important biological signal that regulates many behavior, physiology or cellular processes. This work find light noise can apparently influence the rhythm regularity and induce anticoherence resonance phenomenon. There is always a worst noise intensity that the rhythm regularity is the most dramatically destroyed, however, even stronger noise can counterintuitively minimize this destructive effect. It is of significance to reveal the constructive role of noise in complex living systems.
