When the correlation time $τ_c$ is small enough the firing rate can bbe calculated analytically for small values of the correlation amplitude $α^2$. It is shown that the rate decreases as $\sqrt{τ_c}$ from its value at $τ_c=0$. This limit behavior is universal for integrate-and-fire neurons driven by exponential correlated Gaussian input. The details of the model only determine the pre-factor multiplying $\sqrt{τ_c}$. Two model examples are discussed. rv:
