Voxel clusters of relatively increased fractional anisotropy in attention-deficit/hyperactivity disorder subjects compared to healthy controls are shown in red, overlaid on transaxial sections from a reference brain spatially normalized to the Montreal Neurological Institute stereotactic space, in neurological convention.

<p>Statistical maps are displayed with a statistical threshold of p<0.05, corrected for multiple comparisons (false-discovery rate). 1) Middle temporal gyrus white matter (WM) (right); 2) Middle temporal gyrus WM (left); 3) Superior frontal gyrus WM (right); 4) Middle frontal gyrus (right); 5) Cingulate gyrus (right); 6) Superior frontal gyrus (left); 7) Cingulate gyrus (left); 8) Postcentral gyrus (left). R: right.
