Anticipated synchronization in neuronal motifs

Anticipated 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...

Inhibitory loop robustly induces anticipated synchronization in neuronal microcircuits.

We investigate the synchronization properties between two excitatory coupled neurons in the presence of an inhibitory loop mediated by an interneuron. Dynamic inhibition together with noise independently applied to each neuron provide phase diversity in the dynamics of the neuronal motif. We show that the interplay between the coupling strengths and the external noise controls the phase relatio...

Anticipated synchronization in neuron models

Anticipated synchronization in neuronal circuits unveiled by a phase-response-curve analysis.

Anticipated synchronization (AS) is a counterintuitive behavior that has been observed in several systems. When AS occurs in a sender-receiver configuration, the latter can predict the future dynamics of the former for certain parameter values. In particular, in neuroscience AS was proposed to explain the apparent discrepancy between information flow and time lag in the cortical activity record...

Pseudo-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...
