a Proposed optimal electrode configurations consisting of two, four, six, and eight channels (from top to bottom). b Performance comparison between the proposed optimal electrode configurations and the electrode configurations of commercial wearable EEG devices. The x-axis of the bar graphs represents the electrode configurations. The error bars indicate standard error. * Bonferroni-corrected p < 0.05, ** Bonferroni-corrected p < 0.001, *** Bonferroni-corrected p < 0.0001
