Changes in the shape of the correlation <i>C</i>(<i>D</i>) for a network with <i>N</i> = 800 neurons considering different levels of asymmetry in the network activity encoded in the stored pattern as measured with the parameter <i>a</i> (see main text for the explanation).

<p>Panel A depicts correlation curves for <i>a</i> ≤ 0.45, showing that the correlation <i>C</i>(<i>D</i>) drops around <i>D</i> = 100<i>pA</i> and another maximum starts to emerge at <i>D</i> = 65<i>pA</i>. Panel B illustrates <i>C</i>(<i>D</i>) curves for <i>a</i> ≥ 0.45, showing that the low noise maximum at <i>D</i> = 100<i>pA</i> looses intensity as <i>a</i> decreases. Each curve has been obtained with a single realization of the corresponding network. Other parameters were as in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0121156#pone.0121156.g001" target="_blank">Fig. 1</a>.
