Figure 5

An illustration of the extraction of tractography-based fiber lengths. Image datasets were chosen according to whether motion artifacts were corrected. After eddy-current correction, the probabilistic process was initiated to reconstruct fiber lengths. The seed point was set to the thalamus, and each endpoint is present in the UNC label-map (colorful regions overlaid on a gray morphology atlas). The color-map regions used to mask the image are marked in a table with each anatomical name. The number of asterisks appears the combination of several anatomical regions, which include that * is dorsal and medial superior frontal gyrus, ** is pars triangularis and pars opercularis, and *** is superior, middle, inferior, and medial orbitofrontal gyrus.
