Abstract :
We study the influence of noise modulation on the detection of sub-threshold periodic signals in threshold detectors under the paradigm of stochastic resonance. Particularly, we show that having an input noise amplitude modulated by the input signal can enhance the phenomenon of stochastic resonance. We then apply this result to a neuron model for which the noise modulation mechanism is an intrinsic property coming from the shot-noise nature of the neuron membrane potential
