Numerical study of the influence of recurrent connexions on the signaling in excitable systems: The dynamical effect of noise recycling

Recurrent connexions in dynamical systems provide not only multiple transduction pathway, but also the possibility of the recycling of noise, which may significantly influence the signal character. In this work, its effect is modeled in an excitable system as recycled noise, which includes a delayed stochastic component. Simulation results prove that the noise recycling delay can enhance the noise induced anticoherence resonance in some moderate delay scope. Further investigation suggests that the control effect may come from the additional time scale resonant match introduced by the recycling of noise.
