Effects of tDCS on Alerting, Orienting, and Executive Attention. Participants receiving 30 minutes of 2.0 mA anodal tDCS over right inferior frontal cortex (dark bars) had significantly greater alerting scores from the ANT than those receiving 0.1 mA (light bars). Differences between tDCS groups for scores of orienting attention and executive attention were nonsignificant. Error bars represent standard error of the measurement.
