(color online) (a) Trajectory of system (1)–(4) on the (n₁,V₁) plane for g_K = 4.4 nS. The olive curve is the trajectory of the whole system, and the black and pink curves represent the V₁- and n₁-nullcline. (b) Bifurcation analysis of the fast subsystem with the slow variable as a parameter. The red solid curve and dashed curve describe stable and unstable limit cycles, respectively, the olive curve shows the trajectory of the whole system, and the blue curve is the h₁-nullcline.
