Influence of distance parameter R on global synchrony. N = 200 oscillators with only up-down potentials (p⁺ = 1) was initialized with random phases (A–C) or synchronized phases (D–F). Statistics calculated are average frequency of individual neuron spikes (f; A and D; gray lines indicate intrinsic frequency of 20 s⁻¹), synchrony (z; B and E), and the autocorrelation time of the z time course (τ_AC; C and F). An elongated geometry was used; simulations run for up to N·6,000 iterations or until 40 s elapsed time; statistics calculated for t ≥ 2 s. Gray boxes, individual simulation runs; solid lines, arithmetic mean of individual simulations.
