Stochastic resonance of localized activity driven by common noise

Abstract We study the influence of spatially correlated noise on the transient dynamics of a recurrent network with Mexican-Hat type connectivity. We derive the closed form of the order parameter functional in the thermodynamical limit of neuron number N. Our analysis shows that the network dynamics is qualitatively changed by the presence of common noise. Network dynamics driven by the common noise obtains the global level of fluctuation, which is not observed in a network driven by independent noise only.
