Multiple reentry. The top row represents the deterministic reaction–diffusion (RD) model and the bottom row represents the probabilistic cellular automata (CA) model. (a) Representative snapshot of an electrical wave from electronic supplementary material, videos S7 (top) and S8 (bottom). (b) Entropy of each cell in the cardiac tissue shows a heat map of the entropy in bits over the cell lattice. (c) Mutual information between two cells in the cardiac tissue shows a heat map of mutual information in bits over the cell lattice. Mutual information was computed between a specific cell (green circle) and all the other cells in the same cardiac tissue. (d) Profiles of entropy (blue line) and mutual information (red line) through the cell lattice along the vertical broken line shown in 5b and 5c3, centre, respectively.
