Cooperative Stochastic Effects in Globally Coupled Interacting Neurons;Stochastic Resonance. (Reannouncement with New Availability Information)

摘要

We consider a network of N nonlinearly coupled neuron-like elements subject toLangevin noise and a weak periodic modulation. Through the adiabatic elimination procedure, the dynamics of a single neuron is obtained from the coupled stochastic differential equations describing the network. The bifurcation properties of this 'reduced neuron' model are discussed, together with cooperative stochastic effects (e.g., stochastic resonance) that result from the presence of the modulation....
