FIGURE 5.

Example of phase slips between the θ phase and the peak of Lγ amplitude before, during, and after auditory cues. The time–frequency plot of the normalized power between 30–60 Hz (Lγ) was time-locked to the θ wave (black tracks), and 0 s aligns to the contralateral heel strikes. The peak of Lγ amplitude lies on the descending phase of the θ wave before auditory cues (left panel), in contrast, lies on the ascending phase of the θ wave with cues (middle panel), and lies the between after cues (right panel).
