Simulation of the electrical field of the tACS

(A) Group average (N = 18) of the normalized predicted electrical field distribution of the white and gray matter in MNI space. Note that the efield predictions for the CSF were not transformed to MNI space explaining the interhemispheric gap in the efield model. The cyan circle indicates the preSMA ROI (10 mm sphere around coordinate [11,10,62] based on a previous fMRI study with the same task paradigm).

(B) Relation between normalized predicted electrical field strength within the preSMA ROI and the effect of beta stimulation on peak force in successful stop trials. The shaded area represents the 95% confidence interval.
