Multitasking performance and neurophysiological activity.
(a) Higher multitasking d-prime was observed in tACS group as compared to the control group. (b) and (d) Grand averaged time-frequency representation plots for frontal and posterior electrophysiological activity. (c) and (e) The mean relative power change from pre-stimulation to post-stimulation for frontal and posterior theta, alpha, and beta activity. Error bars represent SEM. **p≦0.01.
