Neurobiologically Realistic Determinants of Self-Organized Criticality in Networks of Spiking Neurons
Figure 6
Relationship between hierarchical modularity, wiring cost and network dynamics.
Statistical significance of power-law distributions of avalanche sizes (black) and durations (red) as a function of network randomization, for (a) nonhierarchical and hierarchical (b) power-law, (c) exponential and (d) linear density scaling functions. Gray lines show the threshold for power-law scaling. Error bars represent the standard error of the mean from
simulations.
