{"pk":24494,"title":"Network-wise transcranial alternating current stimulation with phase lags","subtitle":null,"abstract":"Transcranial alternating current stimulation (tACS) is an efficient neuromodulation technique to enhance cognitive function in a non-invasive manner. Using electroencephalography and functional magnetic resonance imaging, it was investigated whether a tACS with different phase lags between central executive and default mode networks modulated cognitive performance in perception, working memory, and inhibitory control. It was found that phase-lag-dependent tACS mediated improvement in task performance, neurodynamically reflected in task-relevant cortical and subcortical activation as well as prefrontal-based top-down functional connectivity. Our observations provide neurophysiological correlates of network-wise tACS-phase-dependent neuromodulation and a feasible non-invasive approach to effectively modulate fundamental cognitive functions.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Cognitive Neuroscience; cognitive neuropsychology; Brain Stimulation; Electroencephalography (EEG); fMRI"}],"section":"Abstracts","is_remote":true,"remote_url":"https://escholarship.org/uc/item/99q2s62n","frozenauthors":[{"first_name":"Byoung-Kyong","middle_name":"","last_name":"Min","name_suffix":"","institution":"Korea University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2024-01-01T19:00:00+01:00","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/24494/galley/14091/download/"},{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/24494/galley/21399/download/"}]}
