Burst synchronization transition of intracellular Ca2+ oscillations in coupled cell systems

Considering four coupled identical and non-identical bursters with different topological types, both of the different synchronization transition paths and influence of the oscillatory patterns on synchronization are studied. Our results reveal that the phenomena of multi-time scale, phase-locking, chaos and anti-phase synchronization transitions can be separately found in the coupled systems by varying the coupling strength. The above analysis of synchronization transition could provide us with a further clue for better understanding the mechanism of intracellular Ca2+ signaling.
