Figure 4

Dependencies of serial correlations for the two-state switching model on parameter values. (A) Box plots of SRC(1) values measuring correlations between consecutive ISIs for different values of switching rate k_sf (k_fs is varied so that p_fast is constant at 0.6, k_fs = k_sf (1−p_fast)/p_fast. All other parameter values were fixed: p_fast = 0.6, τ_fast = 40 ms, τ_slow = 200 ms, t_abs = 2 ms, and t_rel = 2 ms). (B) Box plots of SRC(1) values for different ratios of τ_fast/τ_slow (all other parameter values were fixed: k_sf = 10⁻⁴/ms, p_fast = 0.6, τ_fast = 40 ms, t_abs = 2 ms, and t_rel = 2 ms). (C) Box plots of SRC(1) values for different values of p_fast using two different values of switching rates k_sf = 10⁻³/ms in black and k_sf = 10⁻⁴/ms in gray (all other parameter values were fixed: τ_fast = 40 ms, τ_slow = 200 ms, t_abs = 2 ms, and t_rel = 2 ms). For each box plot in this figure, 100 trials were performed with each trial consisting of 5000 ISIs.
