Characterization of the anticipated synchronization regime in the coupled FitzHugh–Nagumo model for neurons
We characterize numerically the regime of anticipated synchronization in the coupled FitzHugh-Nagumo model for neurons. We consider two neurons, coupled unidirectionally (in a master-slave configuration), subject to the same random external forcing and with a recurrent inhibitory delayed connection in the slave neuron. We show that the scheme leads to anticipated synchronization, a regime in wh...
متن کاملPseudo-anticipated Synchronization in a Biologically Plausible Model of a Ubiquitous Neuronal Motif
In a broad region in parameter space (K, τ ) the slave system can anticipate the master system: y(t) = x(t+ τ) [1, 2]. A recent series of papers have extended these results to a setup in which the dynamical system is nonautonomous (e.g. fed by noise) and f models an excitable neuron (FitzHugh-Nagumo or Hodgkin-Huxley model) [3, 4]. The fact that anticipated synchronization is verified also in t...
متن کاملAnticipating the response of excitable systems driven by random forcing.
We study the regime of anticipated synchronization in unidirectionally coupled model neurons subject to a common external aperiodic forcing that makes their behavior unpredictable. We show numerically and by analog hardware electronic circuits that, under appropriate coupling conditions, the pulses fired by the slave neuron anticipate (i.e., predict) the pulses fired by the master neuron. This ...
متن کاملCoupling and Feedback Effects in Excitable Systems: Anticipated Synchronization
This paper reviews our recent work on the synchronization of excitable systems in a master–slave configuration and when the slave system includes a delayed self-coupling term. Particularly, we address the existence of the so-called anticipated synchronization, i.e. a dynamical regime in which the slave system is able to reproduce in advance the evolution of the master. This is most remarkable s...
متن کاملAnticipated synchronization in a biologically plausible model of neuronal motifs.
Two identical autonomous dynamical systems coupled in a master-slave configuration can exhibit anticipated synchronization (AS) if the slave also receives a delayed negative self-feedback. Recently, AS was shown to occur in systems of simplified neuron models, requiring the coupling of the neuronal membrane potential with its delayed value. However, this coupling has no obvious biological corre...
