Behavioral data.

<p>Values of all different parameters analyzed in the task are shown, separated for easy and hard discrimination conditions and for sham and anodal tDCS sessions. For Go trials, three mean values are presented for easy and hard discrimination conditions: RTs, Percentage of correct responses and omissions. False alarms represent errors in Nogo trials. Mean stop-signal delay (SSD) refers to the average (SSD) in the two blocks (go for letters, go for numbers), computed with different staircases (see Materials and Methods). The Stop-Signal Reaction Time (SSRT) values presented were computed for each subject and condition using both the integration and the mean methods.</p><p>Behavioral data.
