      (87%). CONCLUSIONS: Vascular lesions demonstrated on intracranial MRA show a high correla­ tion with infarct distribution. MRA provides information adjunctive to conventional MR in a majority of cases. We conclude that MRA is an important component of the complete evaluation of brain infarction.

      1.Introduction. In the development of the central nervous system (CNS), multipotent neural stem cells (NSCs) of ectodermal origin are responsible for the production of all types of neurons and macroglial cells, i.e., astrocytes and oligodendrocytes.1In vertebrates, NSCs arise from the neuroepithelium lining the nascent neural tube.
