Figure 3.

Spatiotemporal cobweb dynamics in concordant alternating spiral waves. (A and B) show the double period (f _1/2) of the cytosolic calcium signaling along the line segments shown in Fig. 2A. The corresponding spatial cobweb dynamics are shown below in (C and D), respectively. The black circles indicate the restitution curve of the respective wave dynamics. The white circles highlight the slope of the intrinsic frequency f at which the spiral wave rotates around the wave singularity, and the obstacle, respectively, where f can be obtained as the interpolation to f ⁻¹ = CTI(CTD = 0) or f ⁻¹ = CTD(CTI = 0).
