(a) Predominant silence-active coefficient (N), (b) coefficient of variation (CV), and (c) local variation (LV) of inter-spike intervals in the parameter space of $D\times I_0$. N, CV and LV are calculated considering a time duration equal to ${10}^6$ s. The initial conditions are $U=-7$ mV and $\dot{U}=0$. In the resonate model, highest LV values do not coincide with the CV ones
