Figure 6

(a) I = 5 mA; (b) I = 7.5 mA; red lines refer to saddle-node bifucations and blue lines refer to homoclinic bifurcations; (sn) qualitative sketches for saddle-node bifurcations, the sequence (a–c) reproduces the generic transition from region P/Q to region Q; (h) qualitative sketches for homoclinic bifurcations, the sequence (a–c) reproduces the generic transition from region P/Q to region P.
