P 95 Frequency-specific after-effects of transcranial alternating current stimulation (tACS) on motor learning

Motor learning is associated with changes in synchronized oscillatory activity at alpha (8–12Hz) and beta (12–30Hz) frequencies. Numerous studies demonstrated that tACS can entrain ongoing oscillatory activity (Antal and Herrmann, 2016) and modulate motor behavior (Pollok et al., 2015; Wach et al., 2013). However, the neurophysiological mechanisms underlying tACS (Antal and Paulus, 2013) and its modulatory effect on motor learning remain ambiguous. Thus, the purpose of the study was to investigate the effects of tACS on the learning of a bimanual visuomotor coordination task and the accompanied oscillatory activity.
