Comparison between estimates of the firing rate and numerical simulations, for the exponential integrate-and-fire model.

<p>Illustration for a given set of parameters ( Hz, mV, mv, ms). From top to bottom: input signal trace; raster of action potentials in a subset of trials; comparison between the numerical PSTH (black) and the LN estimate, the rate model and the adaptive timescale rate model. The values of and indicate respectively the correlation coefficiant and root-mean-square distance between the predicted firing rate and the numerical PSTH.
