Cluster synchronization in neural networks with delayed coupling — •Johannes Pardowitz¹, Judith Lehnert¹, Thomas Dahms¹, Philipp Hövel^1,2, and Eckehard Schöll¹ — ¹Technische Universität Berlin, Germany — ²Bernstein Center for Computational Neuroscience Berlin, Germany

We study zero-lag and cluster synchronization on delay-coupled neural networks, considering simple network motifs and small-world networks of FitzHugh-Nagumo models. We systematically investigate the influence of the network topology and the initial conditions on the dynamical synchronization patterns. In addition, the desynchronization transition induced by additional inhibitory links [1] is discussed.
