Transcranial alternating current stimulation entrains alpha oscillations by preferential phase synchronization of fast-spiking cortical neurons to stimulation waveform

Abstract

Transcranial alternating current stimulation (tACS) can modulate cortical oscillations and associated long-lasting cognitive and behavioral functions in humans. Here, the authors provide in vivo evidence in ferrets on the mechanism of how weak electric fields in tACS can entrain neuronal activity.
