Firing statistics of neural sampling networks.

<p>(A) Shown is the membrane potential histogram of a typical neuron during sampling. The data is that of neuron from the simulation shown in <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1002211#pcbi-1002211-g003" target="_blank">Figure 3</a> (the membrane potential and spike trace of are highlighted in <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1002211#pcbi-1002211-g003" target="_blank">Figure 3</a>). (B) The plot shows the ISI distribution of a typical neuron (again from <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1002211#pcbi-1002211-g003" target="_blank">Figure 3</a>) during sampling. The distribution is roughly gamma-shaped, reminiscent of experimentally observed ISI distributions. (C) A scatter plot of the coefficient of variation (CV) versus the average interspike interval (ISI) of each neuron taken from the simulation shown in <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1002211#pcbi-1002211-g003" target="_blank">Figure 3</a>. The value of neuron from <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1002211#pcbi-1002211-g003" target="_blank">Figure 3</a> is marked by a cross. The simulated data is in accordance with experimentally observed data.
