Abstract
The default mode network (DMN) in the human brain is involved in a broad array of cognitive functions, including creative thinking. Transcranial Electrical Stimulation (TES) is a popular non-invasive brain stimulation. TES has three types: Transcranial Direct Current Stimulation (tDCS), Transcranial Alternating Current Stimulation (tACS), and Transcranial Random Noise Stimulation (tRNS). The mechanisms of each TES method still need to be better understood. This study proposes simulation of the DMN using HD-tDCS, alpha-HD-tACS, high-frequency HD-tRNS, and sham. We intend to reveal how the three TES methods impact DMN activity and connectivity using scalp electroencephalography (EEG).
