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

Figure 6

Sample paths of (scaled). In this case is coupled to a 15 Hz . For comparison with a centered about 6 Hz see Figure 3. Sinusoidal, pulsatile, and biphasic cross frequency coupling is exhibited. Each pulse is about 25 milliseconds in duration, consistent with a bandwidth of 40 Hz. These time-series approximate high-pass filtered neural recordings exhibiting CFC.
