•Cathodal vs. sham tDCS decreases performance in a visuospatial attentional task.•Cathodal compared to sham tDCS decreases brain excitability during task performance.•Cathodal tDCS effects change in rest state vs. during cognitive activity.•We provide clear-cut evidence that cathodal tDCS effects ar...
