| Research Abstract |
T1-weighted MRI images were acquired from formalin-fixed cerebra of cynomolgus monkey fetuses on embryonic days (EDs) 70 to 150 using a high spatial resolution 7-tesla MR system. The results clarified MRI-based chronology of the emergences of cerebral sulci and gyri in this primate. Quantitative analysis revealed a correlation of the emergence of the primary sulci with the development of subcortical white matter bundles. Furthermore, diffusion tensor imaging revealed a spatiotemporal relation of each primary sulci with the specific cortico-cortical long associative fibers.
