EEG analysis of mental concentration in golf putting

We analyzed electroencephalogram (EEG) recorded during golf putting in order to obtain a quantitative index of mental concentration. In previous research, we observed event-related desynchronization in the alpha band; however, the alphaband changes did not clearly reflect mental concentration. EEG was recorded at Fz, Cz, and T3 under three different conditions: rest with eyes open (rest), assumption of putting posture (posture), and actual putting (putting). As a result, 4 participants exhibited large average power in the alpha bands during rest and posture. In the low-theta band, average power was higher during putting than during rest and posture. In addition, an expert putter showed a difference in average power in the low-theta band between successful and unsuccessful putts.
