(color online) Analysis of the system state in two-dimensional bifurcation diagrams. (a) - , (b) – , (c)–(d) – with and 40. The symbols ‘I, II, III, IV’ denote the parameter region corresponding to monostability, excitability, oscillation, and bistability respectively. ‘III-a’ denotes the parameter region corresponding to oscillation with birhythmicity.
