Technical validation. (a) Unified Parkinson’s Disease Rating Scale (UPDRS) Part III scores in medication ON and medication OFF. ***p < 0.01, paired t-test. (b) Topographical maps of MEG-LFP beta-band coherence, averaged over all left-hemispheric and all right-hemispheric electrode contacts, respectively. (c) Example of MEG, LFP, and EMG time-domain data (subject QZTsn6), REST (green), and MOVE (blue) highlighted. (d) Group-average power spectral density of EMG signals for REST (green), HOLD (orange), and MOVE (blue).
