Correlation function <i>C</i>(<i>D</i>) for different number of stored patterns <i>P</i> in a network with <i>N</i> = 2000 neurons.

<p>This shows that as <i>P</i> increases the low-noise maximum of the correlation <i>C</i>(<i>D</i>) increases in intensity and appears at lower level of noise while the second correlation maximum remains unchanged. Each curve has been obtained with a single realization of the corresponding network. Other parameters values 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>.
