Figure 2. PAC frequencies differ between PMC and occipital cortex.

Figure 2

A) Medial view of PMC electrodes (left hemisphere) in subject 2 (labeling as per Fig. 1). B) PAC values (y-axis) for a fixed HG amplitude range across different frequencies of phase modulation (x-axis; 1 Hz bin steps) for example PMC (circled blue in A) and occipital (circled red in A) electrodes. HG amplitude is maximally modulated by theta-phase in PMC, whereas HG modulation is maximal at the alpha range for occipital cortex.
