Simulation results match analysis predictions.

<p><b>A</b>, For 100 repetitions of simulation 1 without feedback inhibition, the mean ⟨<i>v</i>_<i>p</i>⟩ is calculated across trials and plotted against <i>p</i>, and error bars representing 10%–90% confidence intervals are calculated for every fifth pool by case resampling. The rate of increase of ⟨<i>v</i>_<i>p</i>⟩ closely matches the theory (dotted line) except in the first few pools, where the effect of initializing all voltages from zero may have artificially decreased the observed level of synchrony. <b>B</b> For 100 repetitions of simulation 1 with feedback inhibition, ⟨<i>v</i>_<i>p</i>⟩ is plotted with error bars representing 1%–99% confidence intervals calculated by case resampling. From pool 6 on, confidence intervals remain below the upper bound for <math><mrow><mi>E</mi><mo>[</mo><msub><mi>v</mi><mi>p</mi></msub><mo>]</mo></mrow></math> estimated by our analysis (dotted line).
