tACS changed connectivity patterns in the alpha range. Phase-locking values (PLVs) were averaged over time (−400 ms to −100 ms target-locked), and frequencies (IAF ± 2 Hz). Stimulation shifted frontoposterior alpha coherence; while the sham group showed stronger coherence between F8 and left parietal-occipital electrodes compared to F8 and right parietal-occipital electrodes, there was no difference in the stimulation group. Error bars represent standard error of the mean. The star indicates a significant effect.
