| Abstract(in English) | The addition of noise of appropriate intensity improves the transmission of weak periodic signal in the leaky integrate-and-fire neuron model. In this report we study this phenomenon in the frequency domain, where it is characterized by the fact the output signal-to-noise ratio is maximized at an intermediate noise level. To this end, we first compute the interspike interval distribution of the model using a first-passage-time approach, and then derive the power spectral density of the spike train from the interval distribution. In the absence of periodic modulation, we compare the power spectral density with that of gamma and inverse Gaussian distribution. Finally, in the presence of periodic modulation, we investigate the parameter ranges where the model displays stochastic resonance in the sense that the signal-to-noise ratio goes through a maximum as the noise level is increased. |
