<p>The colour maps represent the group-level average EEG signal amplitude expressed as percentage of change relative to baseline (ER%). x-axis: time (s); y-axis: frequency (Hz). Three time-frequency regions of interest were defined: ROI-ERP circumscribing the phase-locked ERP, ROI-ERS circumscribing an early, non phase-locked enhancement of signal power between 10–20 Hz and ROI-ERD circumscribing a long-lasting desynchronisation of alpha-band power. The magnitudes of ROI-ERP, ROI-ERS and ROI-ERD were not significantly modulated by cTBS.</p>
