The bifurcation behaviour of a heterogeneous population. Top: mean voltage at a fixed point (solid stable, dashed unstable), mean ± one standard deviation (dotted), and the maximum and minimum of the mean of V over one period of oscillation (circles), as a function of $I_m$. Bottom: period of the stable periodic orbit. $N=10$, $g_{\mathrm{syn}}=0.3$, $I_s=7.5$.
