Anticipating the response of excitable systems driven by random forcing

TL;DR

This paper demonstrates that unidirectionally coupled neurons can achieve anticipated synchronization, where the slave neuron predicts the master neuron’s pulses, even under unpredictable external noise, through numerical and hardware experiments.

Contribution

It introduces a novel form of anticipated synchronization in neuron models driven by random external forcing, validated by both simulations and electronic circuit implementations.

Findings

Slave neuron predicts master neuron pulses under noise

Anticipated synchronization occurs with appropriate coupling

Experimental validation with electronic circuits

Abstract

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 implementation in 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 anticipated synchronization occurs even when the common external forcing is white noise.
