Transcranial alternating current stimulation (tACS) increases functional connectivity (FC). A: global brain connectivity (GBC) of human motion area (hMT+) increased with tACS, more so in the left hemisphere than in the right hemisphere, and, at least in the left hemisphere, there was no interaction with adaptation. B: FC between hMT+ and the dorsal attention network (DAN) increased with tACS, more in the left than in the right hemisphere. Adaptation did not affect this interaction. These analyses show that 10-Hz tACS increases FC and that at least some of this effect (B) is distinct from the influence of tACS on adaptation.
