Labeling of cortical terminations according to anatomical landmarks.

<p>Cortical terminations of white matter fascicles (e.g. left arcuate fascicle; green) were labeled according to gyri and sulci provided by 3D surface renderings (A) generated from high-resolution T1-weighted magnetic resonance images (B; sagittal section running through the left frontal operculum). a = horizontal ramus of the Sylvian fissure; b = ascending ramus of the Sylvian fissure; c = precentral sulcus; d = central sulcus; e = superior temporal sulcus; 1 = pars orbitalis of the inferior frontal gyrus (Brodmann area [BA] 47); 2 = pars triangularis (BA 45); 3 = pars opercularis (BA 44); 4 = ventral premotor cortex (BA 6); 5 = precentral gyrus (BA 4/6); 6 = superior temporal gyrus (BA 22); 7 = middle temporal gyrus (BA 21).
