Effects of Exogenous Noise in a Silent Neuron Model: Firing Induction and EM Signal Detection

Neuronal intrinsic noise has already shown to play a constructive role in stimuli detection. Here, an exogenous noise, applied to the neuron model as a random membrane voltage perturbation, has been considered. Properly choosing its frequency band, such a noise is able to induce firing activity in a silent neuron and to enhance the detectability of an exogenous signal, representative of an electromagnetic stimulation, through the phenomenon known as stochastic resonance
