摘要:Emerging evidence suggests that transcranial direct current stimulation (tDCS) may improve naming in personswith chronic left hemisphere stroke and non-fluent aphasia. Language improvements beyond naming have not yetbeen thoroughly investigated. Moreover, different investigations have employed different electrode polarities(anodal or cathodal) at different sites (ipsilesional or contralesional cortex), raising the question of whether optimalstimulation parameters vary across aphasic subjects.
