Editorial: Revisiting the Effectiveness of Transcranial Direct Current Brain Stimulation for Cognition: Evidence, Challenges, and Open Questions

Over the past 15 years, there has been an explosion of interest in the use of noninvasive brain stimulation approaches to study the brain. Some studies have suggested that transcranial Direct Current Stimulation (tDCS) in particular can elicit positive effects on performance for many aspects of cognition, including working memory, attention, executive function, language, and numerical competence. A growing literature further indicates that tDCS can provide potentially long-lasting benefits for patient rehabilitation, ameliorating wide-ranging conditions such as aphasia, pain, major depression, tinnitus, and migraine, among other
