Characterisation of the irregular regimes.

<p>Dependence on <i>G</i>_<i>m</i> of the quantities characterizing the patterns of activity shown in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0118443#pone.0118443.g008" target="_blank">Fig. 8</a>, namely the mean values of (a) <i>T</i>_<i>a</i>, (b) <i>T</i>_<i>r</i>, and (c), <i>T</i>_<i>f</i> (c); and of the number of (d) action potentials, <i>N</i>_<i>r</i>, and (e) fast oscillations, <i>N</i>_<i>f</i>. The error bars indicate the standard deviation of the fluctuations of each individual quantity. Each quantity is measured over an interval of at least 6000 s. The quantities shown here have been determiend after averaging over 30 independent realizations of the passive cell distribution.
