a The left middle frontal gyrus (yellow), selected as the (gray matter) stimulation target, overlaid on the MNI brain, created with MRIcroGL (https://www.nitrc.org/projects/mricrogl), is provided on the left. 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. MD values were decreased after the intervention in anodal compared to sham group for those individuals with initially lower MD in the stimulation target. lMFG left middle frontal gyrus, LH left hemisphere, GM gray matter, MD mean diffusivity. Source data are provided as a Source Data file.
