Voltage power spectral densities of subthreshold membrane potential trajectories.

Comparison between the microscopic (thick shaded lines) and the effective (thin solid lines) models. of simulated recordings of the membrane potential were obtained under weak holding currents ({), resulting in membrane potential traces fluctuating around an offset ({). Rare spontaneous spikes were removed from the analysis, excluding the preceding and the following each spike. The spectra have been obtained by applying the Welch method, on moving windows of duration and overlapping by , and subsequently averaging the results.
