Figure 8. Voltage power spectral densities of subthreshold membrane potential trajectories.

Figure 8

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