Hemisphere-specific EEG–EMG associations following gamma–theta stimulation in mild cognitive impairment

The processed datasets supporting the findings of this study are available as Supplementary Material. Specifically, Supplementary Table S1 provides individual-level EEG functional connectivity values (pre-intervention, post-intervention, and change scores; Δr) for all six electrode pairs across nine participants. Supplementary Table S2 provides individual-level EMG change scores (Δ = post − pre) for all four trunk muscles and three spectral features. Supplementary Table S3 presents the complete single-channel EEG–EMG Spearman correlation matrix (14 channels × 8 EMG variables; 112 comparisons). Supplementary Table S4 provides the extended EEG functional connectivity dataset covering all 14 electrode pairs analyzed.
Raw EEG and EMG time-series data are not publicly available due to ethical restrictions governing the use of physiological data from clinical participants. These data may be made available to qualified researchers upon reasonable request to the corresponding author, subject to approval by the Ethics Committee of Japan University of Health Sciences (Approval No. P2103).
