The Effect of Non-invasive Brian Stimulation on Language Production in Healthy Older Adults

Transcranial direct-current stimulation is a non-invasive brain stimulation method that can modify spontaneous cortical activity in targeted brain regions. Anodal tDCS delivered through a positively charged electrode has been found to increase cortical excitability in a targeted brain region. Application of tDCS has been found to improve language production in healthy and brain-injured speakers.
