Simulated neuronal spikes that were utilized in the phase dynamics estimation. Raster displays of a globus pallidus neuronal network and characteristics of the network activity for case A. Spiking activity of the neurons under the various conditions of the variation in applied current and noise (A), distributions of firing periods for the different standard deviations σ_I when σ_N was set to 0.4 (B), and changes in average coherence measure as a function of bin size for different standard deviations of noise σ_N when σ_I = 0 (C).
