Comparison of the linear response of the complex-valued rate model and integrate-and-fire models.

<p><b>A–B.</b> Gain and <b>C–D.</b> phase of the linear response of the QIF (red), EIF (green), LIF (blue) and complex-valued rate (black) models. <b>A.</b> and <b>C.</b> Baseline coefficient of variation of 0.1. <b>B.</b> and <b>D.</b> Baseline coefficient of variation of 0.7. Insets in A and C show gain and phase, respectively, of response near the resonant frequency of 50 Hz. In all cases, the baseline firing rate was 50 Hz.
