Phase mode stability with respect to phase and coupling strength in a symmetric network.

<p><b>A</b> The phase response curve for three values of coupling strength which are indicated by stars in <b>B</b> where the stability of the mode is plotted with respect to coupling strength. In order for the mode to be stable, must be satisfied, so here we note that as coupling strength crosses zero to positive, the mode becomes stable <b>C, D, E</b> From top to bottom, time series of the mean field of simulated networks are shown, corresponding to the coupling values starred in the left, bottom panel. <b>C</b> the order parameter approaches one, due to a positive coupling value, and in <b>D</b>, where no coupling is present, the field exhibits oscillations in its mean field. In <b>E</b>, where coupling is negative, the phases become evenly dispersed.
