Temporal Interference (TI) Stimulation Boosts Functional Connectivity in Human Motor Cortex: A Comparison Study with Transcranial Direct Current Stimulation (tDCS)

Figure 2

TI stimulation cap. O is the position of hot point. A1-A2 are the positions of two electrodes of one tACS channel in which the peak to peak stimulation intensity is 2 mA, and the frequency is 2000 Hz. B1-B2 are the positions of two electrodes of another tACS channel in which the peak to peak stimulation intensity is 2 mA, and the frequency is 2020 Hz. The distance between the position centers of every two electrodes is 4 cm.
