The Kuramoto order parameter as a function of number of microelectrodes and the strength of the control.

<p>Left panel: for each couple (<i>M</i>, <i>γ</i>/4) ∈ [5, 50] × [2, 10] we numerically simulate the controlled system <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1006296#pcbi.1006296.e026" target="_blank">(12)</a> involving <i>N</i> = 100 oscillators interconnected using an all-to-all topology, with coupling parameter <i>K</i> = 0.5 and frequencies <i>ω</i>_<i>i</i> drawn from a normal distribution . Each point is the average over 50 independent realisations (different initial conditions but same frequencies). Right panel: a different visualisation of 〈<i>R</i>〉 allowing to emphasise the relation <i>γ</i>_<i>r</i>(<i>M</i>), <i>r</i> = 0.8 (dashed curve), <i>r</i> = 0.4 (dotted curve) and <i>r</i> = 0.1 (solid curve); let us stress that the latter curves have been draw with a visual guide scope and have not been analytically determined.
