Figure 10From: Phase computations and phase models for discrete molecular oscillatorsLimit cycle and SSA sample path shown on the state space for the Brusselator. Both trajectories start at the same point on the limit cycle. The star traces the limit cycle in clockwise direction, whereas the noisy sample path wanders around though remaining close to the periodic orbit. After some time has passed, the star (of the noiseless path) and the circle (of the noisy sample path) are found to be at different locations. The qualitative difference in terms of phase between these two points is explained by the concept of isochrons.Back to article page
