BACKGROUND AND OBJECTIVE Neuromodulation techniques,including transcraunial direct current stimulation(tDCS),have provided clues concerning the neural circuits underlying normal language,and have helped to explain the pathophysiology of aphasia and its recovery.This review was designed to understand the cumulative data concerning IDCS for the modulation of language,in both healthy individuals and in patients with aphasia.METHODS Data were reviewed from published manuscripts in PUBMED between March of 2005 and January of 2012.From those,64papers were identified,including 10 reviewing aphasic patients,10 reviewing healthy subjects and one combining both aphasic and healthy
