Average Power Spectral Density (PSD) across trials and channels. The figure shows averaged signal power in the 5–30 Hz range, post-filtering. Peaks are observed in the alpha (8–12 Hz) and beta (12–30 Hz) bands, supporting the dataset’s physiological relevance for cognitive and speech-related EEG studies.
