Two-terminal feedback circuit for suppressing synchrony of the FitzHugh-Nagumo oscillators

Abstract

An extremely simple analog technique for desynchronization of neuronal FitzHugh–Nagumotype oscillators is described. Two-terminal feedback circuit has been developed. The feedback circuit, when coupled to a network of oscillators, nullifies the voltage at the coupling node and thus effectively decouples the individual oscillators. Both numerical simulations and hardware experiments have been performed. The results for an array of three meanfield coupled FitzHugh-Nagumo-type oscillators are presented.
