The IAI distribution with $h=0.01/N$ is well fit by an exponential distribution. The theoretical IAI distribution at the lowest level of the external input (shown in red; see also Fig. 9(c)) compared with the fitted exponential distribution (black dashed). The exponential is given by $y=0.028e^{-0.01x}$. This indicates that as the external input is decreased and the system approaches the critical regime the IAI distribution loses the scale-free behaviour seen at higher levels of the external input and is dominated by an exponential
