초록/요약
Early experimental studies in human have shown that the superior longitudinal fasciculus (SLF), a major intrahemispheric fiber tract, is actually composed of four separate components using in vivo diffusion tensor magnetic resonance imaging (DT-MRI). As the development of Track Density Imaging (TDI) improves image resolution, SLF and AF can be subdivided more precisely. In this study we refined dorsal fiber complex (SLF, AF) on the right brain and analyzed the connectivity using 7T TDI data. The results of our study demonstrated that the nine subdivisions and four groups (Supra SLF, SLF, AF medial, AF lateral) could be identified and their functional identities have been interpreted.
