Example whole-brain tractography image used to derive structural connectivity networks. Top view of the tractography image derived from diffusion tensor imaging data from a healthy control subject used in the study, ‘Abnormal brain network organization in body dysmorphic disorder.’ The posterior brain appears at the bottom of the image. Deterministic tractography was calculated in Diffusion Toolkit (http://trackvis.org/dtk), and the image was created using TrackVis (http://trackvis.org). Fibers are colored based on predominant direction: green for anterior <-> posterior, red for left <-> right, and blue for dorsal <-> ventral. Structural connectivity networks were derived from these tractograms in individuals with body dysmorphic disorder and healthy controls. Donatello Arienzoa, Alex Leowa,b,c, Jesse A.
