Modulating Phonological Short-Term Memory in Stroke Survivors With Aphasia Using Transcranial Alternating Current Stimulation.

ABSTRACT: BackgroundShort-term maintenance of phonological information is critical for language production and comprehension, and is often impaired in stroke survivors with aphasia.ObjectiveIn this pilot study, we investigated whether brain oscillatory activity underlying phonological short-term memory (pSTM) can be influenced by transcranial alternating current stimulation (tACS) in stroke survivors with aphasia (SWA).MethodsIn a within-subject, single-blinded, sham-controlled study, 13 SWA received theta-tACS (4-7 Hz) targeting left temporoparietal and inferior frontal regions across 3 tACS conditions (in-phase, anti-phase, and sham; 20 minutes each). Participants completed an adaptive delayed match-to-sample task with spoken consonant-vowel strings (2-8 syllables) before, during, and after stimul
