Repeating avalanches and similarity matrices produced by cortical tissue and by the model. A, Ordered similarity matrix showing groups of similar avalanches from acute slice data. Matrix of all avalanches of length 5 compared to each other for Boolean similarity. Scale bar indicates similarity (ranging from 0 to 1), with highest similarity coded black. Arrows (1: 2: 3) point to example regions of the matrix with groups of similar avalanches. Comparable similarity matrices are also found in data from cultures (see [17]. B, Ordered similarity matrix produced by the model appears like matrix from data, with similar sized groups along the diagonal. C, Groups of similar avalanches produced by the model, matching the numbered regions (1, 2, 3) from the model's similarity matrix. Note that avalanches within groups share general, not exact, resemblance. D, Groups of similar avalanches produced by the data from regions (1, 2, 3) in the data similarity matrix.
