a A canonical image of the thresholded probabilistic tract, overlaid on the Montreal Neurological Institute (MNI) brain, created with MRIcroGL (https://www.nitrc.org/projects/mricrogl). To generate the canonical image, individual tracts from all participants were normalized, converted to binary images and then summed (color coding reflects the probability of voxels to be present in 33–100% of the participants). b Means (black diamonds for anodal and white diamonds for sham) and individual data points (single circles in orange/red for anodal and lightblue/darkblue for sham). Box plots indicate median (middle line), 25th, 75th (box), and 5th and 95th percentile (whiskers). n = 46 independent participants. FA along the tracts was increased after training in training group that had received anodal compared to sham tDCS. FA, fractional anisotropy. Source data are provided as a Source Data file.
