Fig. 6. — Stimulus-induced pattern formation in the network of 200 × 200 IO oscillatory units. During the stimulation, the units are uncoupled. The initial phases are randomly distributed in the interval [0, 2π]. The stimulus has fixed duration τ_st = 0.4T, T = 51.1 and variable amplitudes. The stimulus amplitude pattern is taken from digitized grayscale 200 × 200 image, , where c[i, j] ∈ [0,1] is the matrix of real numbers corresponding to the grayscale levels. The image c[i, j] contains a picture reproduced with permission from www.beautifulbugs.com. (A) Initial random distribution. (B and C) Phase cluster formation for excitatory stimulus pattern, I¹_st = 0.4, I²_st = 3.5. Phase distribution after the stimulation nicely reproduces the desired bug picture. After the stimulus, the oscillators group with required phases. The images are plotted with the same grayscale grade as the phase values interval [0,2π].
