Abstract:We study the influence of broken connectivity and frequency disorder in systems of coupled neuronal oscillators. Under nonlocal coupling, systems of nonlinear oscillators, such as Kuramoto, FitzHugh-Nagumo or Integrate-and-Fire oscillators, demonstrate nontrivial synchronization patterns. One of these patterns is the "chimera state", which consists of coexisting coherent and incoherent domains. In networks of biological neurons, the connectivity is not always perfect, but might be locally broken, or interrupte… Show more
