Abstract
The nonlinear transformation of an external noisy signal by an array of noninteracting elements with internal noise is considered. The array simulates a neuronal system that processes spike trains. It is shown that increasing the number of array elements entails significant extending of the stochastic synchronization region and improvement of the signaltonoise ratio (SNR). The effects are demonstrated for arrays of triggers, overdamped bistable oscillators and FitzhughNagumo systems. The interrelation between SNR improvement and the efficiency of information processing is discussed.
