A Time-Series Model of Phase Amplitude Cross Frequency Coupling and Comparison of Spectral Characteristics with Neural Data

Figure 4

Spectra of the stochastic model . The sinusoidal, pulsatile, and biphasic ’s each contribute to the spectrum in a different way. The spectrum associated with computed with the pulsatile function of is similar to the spectrum estimated from actual neural recordings (see [5]). The spectra associated with sinuosoidal, pulsatile, and biphasic exhibit side-lobes consistent with the convolution appearing in (13), (21).
