On various types of synchronization in networks of coupled neurons — •Philipp Hövel1,2, Alexander Fengler1, Alexander Heesing1, and Eckehard Schöll1 — 1Technische Universität Berlin, Germany — 2Bernstein Center for Computational Neuroscience Berlin, Germany
Research on complex networks continues to receive more and more attention since the last decades both from a data-driven and dynamics-driven perspective. In the latter case, collective and cooperative dynamics of coupled systems forms a central phenomenon that is of large interest in various fields. These range from social science and economics to biology, physics, and neuroscience and beyond.
In our contribution, we discuss the synchronization of coupled integrate-and-fire neurons with partial reset in various network topologies. These include all-to-all, ring, and scale-free networks. We find a transition from complete synchronization via cluster synchronization to desynchronization in dependence upon the reset parameter. Our results are based on numerical simulations, which we complement by analytical considerations.
