Simulation of 10,000 oscillators per community with $L=-2$ (A and C) or $L=2$ (B and D) and $K=5$ (A and B) or $K=7$ (C and D). The time step is set at $\mathrm{d}t=0.01$. The top images show the synchronization levels ($r_1$ and $r_2$) and the bottom the average phases (${\mathrm{\psi }}_1$ and ${\mathrm{\psi }}_2$). The phases are plotted in a way that the different communities can be seen as the 2 components of activity in the suprachiasmatic nucleus. The time on the y-axis can be regarded as consecutive days. (A) and (B) show the case in which $r_1$ and $r_2$ are the same, whereas (C) and (D) show the case in which they differ at first but both approach 1 when the stable state is reached.
