Reaction-Diffusion systems of nonlinear partial differential equations are used to model quite a few scientific phenomena. We have used a specific system, the FitzHugh-Nagumo one, to study new methods of generating spiral pairs and spatiotemporal periodic structures in 2D, and 3D repeat ing scroll rings in excitable media. Results are important in different fields, the electrical information transfer and arr hythmias in the heart, chemical reactions such as the Belousov-Zhabotinsky ones and possibly abnormal brain waves.
