This study aims to investigate the efficacy of transcranial alternating current stimulation (tACS) combined with linguistic training for patients with chronic post-stroke aphasia. Thirteen patients will participate in a randomized crossover clinical trial. Their naming ability will be assessed before and after two-weeks of therapy (with 16 days of washout) supported by either 75Hz tACS or sham stimulation. The stimulated cortical area will be selected individually based on the results of functional magnetic resonance imaging.
