Complex transitions between spike, burst or chaos synchronization states in coupled neurons with coexisting bursting patterns*

Burst phase synchronization. (a) Chaos-(1, 2) bursting; (b) from burstings of two isolated uncoupling neurons to chaos-(2, 3) bursting of coupled neurons; (c) from burstings of two isolated uncoupling neurons to chaos-(2, 3, 4) bursting of coupled neurons. Dashed lines in (b) and (c) represent the time of coupling strength changed from 0 to a nonzero value. From top to bottom: spike train of neuron 1, spike train of neuron 2, spike phase difference (Δ ϕ ( t )), and burst phase difference (Δ Φ ( t )).
