<p>A) Network motif corresponding to a full Boolean adder. Same stipulations as for <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0026467#pone-0026467-g003" target="_blank">Figure 3a</a>. B) Temporal evolution of for the three inputs (, and ) and two outputs ( and ) of the adder. The synchronization level is calculated with respect to the reference signal for the three inputs, and with respect to for the outputs.</p>
