Abstract：Transcranial electrical stimulation(tES)can affect the electroencephalogram(EEG)state of hu-man body accordingly,so it can intervene in human body's emotion,memory and sleep state through the current stimulation of specific frequency.In this study,transcranial pulsed current stimulation(tPCS)was used to investigate the effects of different stimulation prescriptions of 0.2 mA,0.4 mA,and 0.6 mA at a stimulation frequency of 5 Hz on EEG signals in the prefrontal region(F3 anode and F4 cathode).The power spectral density,energy percentage and power ratio analyses of the acquired EEG data showed that the experimental group with 0.6 mA electrical stimulation increased the energy of the Theta band(4～8 Hz)and the energy of the first half of the Alpha band(8～10 Hz),and that this phenomenon was more pro-nounced in the central(Fp1)and parietal(C3)regions of the left brain area.It was also found that the stimulus prescription of 5 min、5 Hz、0.4 mA had a higher post-stimulus effect on the Theta band energy percentage than 5 min、5 Hz、0.6 mA.
