The transition of the system between the low- and high-activity stages. (A) Snapshots of the patterns at low- and high- activity stages for different values of the inhibition strength: (1) weak (\({k}_{0}=0.18\), \({s}_{2}=0.7\) for quasi-static and \({k}_{0}=0.2\), \({s}_{2}=0.75\) for oscillatory regimes), (2) balanced (\({k}_{0}=0.2\), \({s}_{2}=0.9\) for quasi-static and \({k}_{0}=0.26\), \({s}_{2}=1.05\) for oscillatory regimes), and (3) strong (\({k}_{0}=0.2\) 2, \({s}_{2}=1.1\) for quasi-static and \({k}_{0}=0.2\), \({s}_{2}=1.1\) for oscillatory regimes). (B) Snapshots of the system at the beginning of the high-activity stage. Arrows indicate the direction of wave propagation. Dashed outlines indicate vector alignment on a larger scale. Images in (A), (B) show two merged channels: green for the activator and red for the inhibitor. (C) The activity amplitude and temporal autocorrelation for the oscillatory low-activity stage with weak negative feedback (left), balanced activation and inhibition (center), and strong negative feedback (right).
