Control of chimera states in multilayer networks of FitzHugh-Nagumo neurons — •Giulia Ruzzene and Ralph G. Andrzejak — Universitat Pompeu Fabra, Barcelona, Spain

Chimera states are a widely studied phenomenon in nonlinear science. In oscillator networks, a chimera state is defined as the coexistence of synchronous and aysnchronous groups of nodes. Many analogies have been established between chimeras and natural phenomena, especially with brain dynamics. Here we study the dynamics of a two-layer network of FitzHugh-Nagumo oscillators, which model neuronal dynamics. Chimera states have been observed in this configuration, but only a few studies also deal with the topic of control of chimeras in multilayer networks. Here we apply a control mechanism that we previously developed for chimeras in single-layer networks of phase oscillators. We study the interplay of the control method with the multilayer configuration and show the parameter regions in which the control is effective.
