Figure caption: Brain modulation using 2×2 HD-tDCS Montage. A. 3D rendered head built from the MRI derived segmentation masks used in the study. Anode electrodes (red) were placed over C3 and C5 and Cathode electrodes were placed over FC3 and FC5. B. Skin,skull, and CSF masks are suppressed to reveal the underlying gray matter mask. C. Induced cortical surface electric-field directional plot for 2 mA stimulation. Red denotes inward (anodal) stimulation while blue denotes outward (cathodal) stimulation. D. Induced cortical surface electric-field magnitude plot for 2 mA stimulation.
