Raster plots for different levels of the external input with the saturating activation function. Neuronal firing during the first 2 seconds of example simulations with $h=1/N$ (a), $h=0.1/N$ (b) and $h=0.01/N$ (c). For all three simulations $w=1$, $\alpha =0.25$ and $N=800$. Comparing with Fig. 3 we find that while in this case the firing rate is lower (note the longer time scale over which the raster plot is displayed) the overall pattern is the same, with the avalanches becoming more distinct with lower levels of the external input
