Effects of transcranial direct current stimulation (tDCS) on behaviour and electrophysiology of language production

► Sham-controlled combination of tDCS and EEG in overt language production. ► Electrophysiological and behavioral modulations induced by prefrontal A-tDCS. ► Online A-tDCS enhanced event-related potentials during picture naming. ► Reduction of delta activity after A-tDCS during picture naming and the resting state.
