Summary:
Stochastic resonance (SR) is a phenomenon involving noise is used to enable state transitions in a bistable or threshold system driven by subthreshold signals. Recently, SR has been observed in such systems driven by internal noise or fluctuation. In this study, we used a unidirectional circular network with nonlinear oscillators as a potential system to induce SR by using internal noise. These oscillators were connected with four neighboring oscillators that have different connection strengths depending on the distance to a destination oscillator and generated internal noise to induce SR. We observed the classical SR characteristics between the correlation value and internal noise intensity.
