Synchronization of viscoelastically coupled excitable oscillators

Viscoelastically coupled excitable oscillators exhibit an interesting range of synchronization patterns due to the interplay of autonomous oscillation and refractory period following an excitation. The viscoelastic coupling effectively introduces a delay to the coupling of such oscillators. As an example of this class of coupled oscillators we study individually beating spatially separated cardiomyocytes surrounded by an extra-cellular matrix via numerical simulations. We investigate the synchronization of a linear chain of two or more coupled cells. Depending on the viscoelastic properties of the coupling different synchronization patterns (asynchrony, in- or anti-phase, 1:1, n:n) occur.
