Stochastic oscillations are a ubiquitous phenomenon in neural systems. We study the role of these oscillations in an analytically tractable model, the stochastic perfect integrate-and-fire neuron with narrowband (harmonic) noise. The latter represents stochastic oscillations. We obtain approximations for the firing statistics including interspike interval density, serial correlations and power spectrum of the spike train. We apply our formulas to experimental data of electro-sensory receptors in the paddlefish and show how to infer intrinsic parameters of this system from its firing statistics.
