We study collective failures in biologically realistic networks that consist of coupled excitable units. The have broad-scale degree distribution, high modularity, and small-world properties, while the dynamics is determined by paradigmatic FitzHugh–Nagumo model. consider different coupling strengths, bifurcation distances, various aging scenarios as potential culprits failure. find for intermediate network remains globally active longest if high-degree nodes are first targets inactivation....

Pancreatic beta cells are coupled excitable oscillators that synchronize their activity via different communication pathways. Their oscillatory manifests itself on multiple timescales and consists of bursting electrical activity, subsequent oscillations in the intracellular ${\mathrm{Ca}}^{2+}$, as well metabolism exocytosis. The coordination intricate multicellular level plays a key role regulation physiological pulsatile insulin secretion is incompletely understood. In this paper, we...

When individual oscillators age and become inactive, the collective dynamics of coupled is often affected as well. Depending on fraction inactive or cascading failures that percolate from crucial information exchange points, critical shift toward macroscopic inactivity in oscillator networks known aging transition. Here, we study this phenomenon two overlayed square lattices together constitute a multilayer network, whereby one layer populated with slow Poincaré other fast Rulkov neurons....
