    • Experiments were carried out with the catalyst of the light-sensitive BZ reaction, (Formula presented) immobilized in a thin slab of silica gel. The silica gel medium was prepared by acidifying a solution of (Formula presented) (w/w) (Formula presented) and 2.0 mM (Formula presented) (where (Formula presented)-bipyridyl) with (Formula presented) and casting a uniform (Formula presented) layer onto a microscopic slide. The gel was continuously fed with fresh, catalyst-free BZ solution in a thermostated reactor to maintain constant, nonequilibrium conditions 19. The chemical composition of the reaction mixture was (Formula presented) (Formula presented) malonic acid, (Formula presented) bromomalonic acid, and (Formula presented) corresponding to excitable conditions where meandering spirals are observed in the unperturbed system

    • The gray level is linearly proportional to concentration over the experimental range, where the camera response to intensity is logarithmic. We measure gray level between 0 and 255 and divide by 255 to obtain the scaled concentration, which we treat as dimensionless

    • The separation distance is the distance between the spiral tips in the composite image composed of the pixelwise superposition of the two systems. The superposition is exactly the same as that during the coupling of the systems
