Optimization results of 61-channel montage when the region of interests (ROIs) were the lateral intraparietal area (LIP) and frontal eye field (FEF) with an optimal stimulation phase of the LIP leading the FEF by 120°. (a) Optimal injection current amplitude (left) and phase (right) distributions for all 61 channels. (b) Electric field amplitude (left) and phase (right) distributions under the optimal injection current condition. (c) Optimal injection current amplitude (left) and phase (right) condition of electrodes exceeding 0.1 mA in the injection current amplitude. (d) Electric field amplitude (left) and phase (right) distributions under the optimal electrode condition over cortical regions where the electric field amplitude was greater than 0.05 V/m.
