Neuropsychological performance in errors in the response inhibition task: “Online” vs. “offline” results.

Standardized data (t-scores) of neuropsychological performance of errors in the response inhibition task separated for patients that engaged in the task during (“online”–left figure) vs. after (“offline”–right figure) stimulation separated by time of measurement and group (black = 2 mA of tDCS over the left DLPFC, grey = sham condition). Depicted is the respective group mean together with the standard deviation. Lower t-scores indicate better performance. * = significant interaction effect TIME*GROUP.
