Fig 1.
tDCS electric field distribution estimate.
Results of the electric field distribution estimate are shown for the anode electrode over the rIFG (F6-FC6) and the cathode electrode over the left OFC. The electric field strength is scaled from 0 (minimum: blue) to 0.4 mV/mm (maximum: red).

Behavioral results: Anodal vs. Sham stimulation.
Box plots representing the RT HIT, FA rate and efficiency index in anodal and sham stimulation (a, b and c). Individual subject’s data points, the median (horizontal line), the mean (cross), and confidence intervals (Tukey whiskers) are represented.

Functional neuroimaging results: Stimulation (Anodal; Sham) by Condition (Go; NoGo) Interaction.
Results are shown on a normalized single-subject brain in the MNI space. Contrasts are represented at pFWE< 0.05 corrected at voxel level (min cluster size = 3, red) and to facilitate visualization pFWE< 0.3 in yellow). Histograms on the right indicate the amplitude of the effect (Arbitrary Unit: A.U) for each condition at clusters’ local maxima with standard error bars. MFG = middle frontal gyrus, IFG = inferior frontal gyrus, SMA = supplementary motor area (see supplementary materials for statistical details).
