English: Comparison between anatomic dissections using the fiber dissection technique and tractography. Qualitative analysis of tract reconstruction using DTI; b0 images of the contralateral hemisphere are used as background for spatial orientation. (a) gross dissection, lateral view; U fibers, SLF, IFO, the nucleus of CL, PT and GP, as well as part of UNC were removed. (b) tractographies. AC is divided into anterior and posterior arm. Whereas, in dissection, it is not possible to identify clear borders between parallel structures and the exposure of a bundle that may require the destruction of a more superficial bundle, tractography enables overlaying of segmented structures using different colors to provide a new view of the relationship between different bundles. AC anterior commissure; ILF inferior longitudinal fasciculus; FP frontopontine fibers; IFO inferior fronto-occipital fasciculus; PP parietopontine fibers; PT putamen; SLF superior longitudinal fasciculus; SS sagittal stratum; CST corticospinal tract; GCT geniculocalcarine tract; UNC uncinate fasciculus
