Weakly nonlinear response of noisy neurons by Sergej O Voronenko, Benjamin Lindner

“…We calculate the instantaneous firing rate of a stochastic integrate-and-fire neuron driven by an arbitrary time-dependent signal up to second order in the signal amplitude. …”

Theory of spike-train power spectra for multidimensional integrate-and-fire neurons by Sebastian Vellmer, Benjamin Lindner

“…Multidimensional stochastic integrate-and-fire (IF) models are a standard spike-generator model in studies of firing variability, neural information transmission, and neural network dynamics. …”
