Synchronization is an emergent phenomenon that occurs in a variety of systems, including arrays of lasers, blinking fireflies, and neurons firing in the brain. One might also be familiar with the demonstration of many classical pendulums sitting on a table - despite starting with random phases, the entire system eventually becomes phase locked. In this talk we will consider systems that can be modelled as globally coupled oscillators, also called “all-to-all” coupling. We will start by deriving the Kuramoto model for such systems and briefly discuss the characteristics of a system that are required for global synchronization. Finally, a recent model describing the activity of neurons as a network of excitatory and inhibitory neurons will be presented. (Sadilek, M. and Thurner, Sci. Rep. 5, 10015 (2015))
