Mechanisms of Firing Patterns in Fast-Spiking Cortical Interneurons
Figure 8
Dependence of the Averaged Delay Duration on the Noise Variance, D
Black line: the delay duration, tdelay, computed and averaged over 50 trials of the noisy external current step is plotted as a function of log(D). Parameters: θm = −24 mV (small window Na+ current), gd = 0.39 mS/cm2, and Iapp = 3.08 μA/cm2. Gray lines: one standard deviation confidence limit of the averaged tdelay. Red line: fitting to the simulation results using the analytical prediction for small D (Equation 4). The arrow on the y-axis indicates the value of tdelay for a noiseless input (D = 0).
