Figure 4.

Blue cross highlights the cluster local maxima on the posterior portion of the right inferior fronto-occipital fasciculus (r-iFoF) where white matter volume is increased when comparing attention-deficit/hyperactivity disorder (ADHD) and first-degree relatives with control subjects (Montreal Neurological Institute coordinates x = 15, y = −90, z = 4; cluster level correction, familywise error p < .05). Right panel shows mean volume estimates extracted from this cluster of 288 voxels, according to group). *For significant differences. Bars represent standard error of the mean.
