Abstract

Abstract

En 中文
Transcranial alternating current stimulation (tACS) with a combined theta-gamma (TG) waveform can boost human motor performance, but its effects on primary motor cortex (M1) plasticity remain unclear. This study investigated the effects of concurrent TG tACS and repetitive paired-pulse transcranial magnetic stimulation (rppTMS) on M1 excitability and plasticity.
