EEG channels contribute to the final overall best results in the experiments

Experiment	Channel number (spatial position of scalp electrode*)
1	56 (AF4), 54 (AF7), 25 (CP6), 36 (FT7)
2	32 (C2), 49 (Fz), 30 (C1), 4 (PO7), 15 (P4), 34 (C6), 37 (FC5), 39 (FC1), 47 (F3)
3	21 (CP1), 53 (F8), 36 (FT7), 3 (O2), 18 (TP7), 1 (O1), 9 (P7)

*Within the parentheses, capital letters A, C, F, O, P, and T refer to the anterior, central, frontal, occipital, parietal, and temporal positions of the scalp electrodes (channels) that overlie the corresponding brain regions; a small letter z refers to the mid-sagittal centerline. There is no anatomical “anterior” or "central” lobe, but the terms were used to describe the relative positions of the channels to the frontal lobe channel. Even numbers represent left-brain channels, and odd numbers represent right-brain channels
