Computational method to determine the optimal individualized position of the tDCS montage. A Head model segmentation. The volume conductor of the head model of each participant will be constructed from the segmentation of MRI data. B Computational modeling of a representative example. The individualized electric field on the cerebellum using a bipolar montage (anode in yellow and cathode in blue) will be simulated. C Optimal montage position. The optimal location of the anode that maximizes the electric field strength (maximum and average) on the region of interest (lobule VI) is selected from a grid of 13 × 11 positions
