“…The characteristic channels selected for statistical analysis of EEG were frontal region (Fz, F3, F4, FCz, FC3, FC4), parietal region (Pz, P3, P4), central region (Cz, C3, C4, CP3, CP4), temporal region (TP7, TP8, T7, T8, P7, P8), and occipital region (POz, PO3, PO4, Oz, PO7, PO8) [31]. The subjects' EEG data were acquired via Neuroacle EEG Recorder V2.0.1, a toolbox of the software Matlab 2016 (Math Works, USA), with a sampling frequency of 1000 Hz and electrode impedances all less than 5 kQ.…”
