Effects of spark properties on dynamics.
Shown in each panel is the number of sparks (nk) versus pacing period (T) from the iterated map model (Eqs 7 and 8). (A) Control, which was modified from Fig. 5A by changing υ and κ (υ = 0.4 and κ = 0.1). (B) Reduced primary spark probability (α0 = 0.25). (C). Reduced recruitment (γ0 = 0.5). (D) Tβ = 600 ms. (E) Tβ = 700 ms. (F) In the presence of spark amplitude restitution for τr = 0 ms (black, the same as A), 100 ms (red), 200 ms (blue), and 300 ms (cyan).
