TL;DR

The corkscrew shape of the oscillator's phase-resetting surface, predicted by the Culex model and verified here, suggests that the circadian dynamic system has a limit cycle.

Abstract

TheCulex flight activity circadian oscillator, free-running in darkness, was perturbed by single bright light pulses. The phase and duration of the pulse were varied systematically (Winfree's "singularity trap" procedure) revealing the oscillator's phase-resetting surface. The corkscrew shape of this surface, predicted by theCulex model and verified here, suggests that the circadian dynamic system has a limit cycle.
