A two-layered neural network composed of sensory neurons and cortical neurons were examined. It was shown that with small noise cortical neurons fire synchronously and intervals of synchronous firing robustly encode the signal information. A positive role of noise in the brain was suggested in a meaning different from stochastic resonance, coherence resonance and deterministic chaos.
