Abstract

Transcranial alternating current stimulation (tACS) is a widely used non-invasive regulation method. Although tACS plays a role in improving cognitive function and is gradually introduced into clinical trials of psychiatry, its mechanism of action has not been well explained. Microstate analysis is a method to extract information from EEG signals, considering all electrode signals to establish the global representation of functional state, which can evaluate the function of large-scale brain network. In this paper, the changes of microstate parameters in resting state EEG pre and post 40Hz and sham tACS were compared. The results showed that tACS effectively decreased microstate C and effectively increased microstate D. Our research shows the feasibility of microstate analysis in studying the internal mechanism of tACS.
