Transcranial alternating current stimulation (tACS) can non-invasively alter neuroelectric activity in the brain by applying weak time-varying electric currents via the scalp. Complex patterns of electric brain activity can take the form of traveling waves - spatially coherent brain rhythms that gradually propagate through the neocortex. Traveling waves are crucial for the temporal coordination of informational flow in the brain. Using the novel traveling-wave transcranial alternating current stimulation (tACS) approach, the investigators will explore the effects of frontal-to-parietal and parietal-to-frontal traveling waves on working memory performance and brain electrophysiology in adults.
This study will assess the impact of traveling wave transcranial alternating current stimulation (tACS) on working memory performance in adults.
