Phase locking (PLV) between LFP and EEG in high beta (20–35 Hz). (A) The PLV during Shake is lower than that during Hold and Press for all scalp electrode sites (ipsi: ipsilateral to STN; contra: contralateral to STN). (B) For central scalp electrodes, the PLV is lowest during Shake in all N = 12 recordings (* = p < 0.05, paired Wilcoxon test).
