Impact of intermittent ON–OFF CR stimulation on the ensemble of aEIF bursting neurons (Equation 7). (A) Maximal admissible number n_max of OFF cycles vs. the number of stimulation sites N_s for σ = 0.5 (black diamonds) and σ = 4 (red circles). The synchronization threshold is considered 〈r〉_opt = 0.25, see section 3.2 for definition. (B) Time courses of the ensemble mean filed $\langle V\rangle =N^{-1}{\displaystyle {\sum }_{j=1}^N{V}_j}$ (black curve) and the first order parameter R₁ (red curve, scale on the right vertical axis) between two successive ON epochs (indicated by dashed vertical lines and bars on the top of the plot). Parameters σ = 0.5, n = n_max = 40, I = I_opt = 392 pA, and N_s = 5. (C) The same as in (B) for the parameters σ = 0.5, n = n_max = 14, I = I_opt = 460 pA, and N_s = 2. Number of ON cycles m = 3, and other parameters as in Figure 12.
