The Validation and Biological Index Studies on the Improved Social Function of ASD by 40 Hz tACS

The central electrode is placed in the CP6 and the other four electrodes are placed around the CP6. 40 Hz tACS group participants will receive alternating current stimulation (40Hz, 2.0mA, 20min/time, three times a day, 21 times in total) for 1 week. Subjects in the placebo comparator group will receive sham tACS for 1 week, which mimics the tACS intervention in terms of electrode placement and session frequency. However, the device will deliver a 0mA current, ensuring no actual stimulation occurs.
