Fig. 1

Dynamics of the oscillators with pulse delayed coupling and derivation of the discrete maps. Dots depict the moments of spikes emission. (a) Single oscillator with delayed feedback and (b) its dynamics. Each spike produced arrives to the oscillator after delay time τ. Tj are the inter-spike intervals. (c) Two oscillators with mutual delayed coupling and (d-e) their dynamics. A spike produced by each oscillator arrives to another one after delay time τ. (d) Near-in-phase dynamics, δj are the time lags between the oscillators. (c) Near-antiphase dynamics, Sj are cross-spike intervals.

Fig. 3

The bifurcation diagram of two oscillators with mutual delayed coupling. The observed ISIs of the established dynamical regimes are plotted versus the time delay. Blue lines stand for near-in-phase, red for near-antiphase regimes. Theoretically predicted regular regimes are plotted by thin lines, solid for stable and dashed for unstable regimes. Diamonds depict saddle-node or period-doubling bifurcations, while stars depict multi-jitter bifurcations. Thick dots depict the numerical results. Note that almost everywhere the stable branches predicted by the theory are covered by numerically observed dots.

Examples of jittering regimes of two oscillators: (a) antiphase jittering at τ = 1.95 and (b) in-phase jittering at τ = 2.4. The upper panels show the temporal dynamics of the ISIs for both oscillators, the bottom panels show the moments of spike emission. Note that in the case of in-phase jittering the ISIs for the both oscillators coincide, which means that they remain fully synchronized.
