Multi-chimera States in the Leaky Integrate-and-Fire Model

Tsigkri-DeSmedt, N.D.; Hizanidis, J.; Hövel, Philipp; Provata, A.

We study the dynamics of identical leaky integrate-and-fire neurons with symmetric non-local coupling. Upon varying control parameters (coupling strength, coupling range, refractory period) we investigate the system's behaviour and highlight the formation of chimera states. We show that the introduction of a refractory period enlarges the parameter region where chimera states appear and affects the chimera multiplicity.
