Stochastic resonance in a single bistable neuron and its application

This paper investigated the response of a single bistable neuron to a weak periodic signal by the addition of the variable amount of noise. The results show that the neuron transduces the signal optimally when a certain amount of noise is present, i.e., stochastic resonance (SR). By the signal-to-noise ratio (SNR) measure, the neuron's applicability and superiority for weak signal detection purposes are illustrated. The research enlarges the application scope of neuron to nonlinear signal processing.
