Chaotic synchronization between coupled pancreatic beta-cells

The paper first describes the main bifurcation structure for a typical mode l of an insulin producing pancreatic beta-cell. Considering a system of two coupled identical and chaotically spiking beta-cells, the paper continues to examine the bifurcations through which low periodic orbits embedded in t he synchronized chaotic state lose their transverse stability and produce t he characteristic picture of locally and globally riddled basins of attract ion. We discuss the different types of riddled basins with the associated p henomena of attractor bubbling and on-off intermittency.
