Transcranial alternating current stimulation (tACS) has been known as a well-established non-invasive electrical stimulation method of human cortex. A number of researches on the efficiency of tACS discovered that it could directly modulate human cortex function by applying of oscillatory currents on the human scalp. Until now, the electrophysiological evidence of tACS remains unclear. In this study, we delivered α-tACS or sham stimulation over the prefrontal cortex of 20 healthy participants and recorded the rest EEG before and after the stimulation to calculate alpha power. The results showed that α-power of both fixed and individual α-band elevated after α-tACS, while the phenomenon did not appear in sham group. We could draw a conclusion that α-tACS could enhance α-oscillation and modulate rhythmic brain activity specifically.
