Description:
During early development of the mammalian cerebral cortex, young neurons migrate outward from the site of their final mitosis in the ventricular zone into the cortical plate, where they form the adult cortex. Time-lapse confocal microscopy was used to observe directly the dynamic behaviors of migrating cells in living slices of developing cortex. The majority of cells migrated along a radial pathway, consistent with the view that cortical neurons migrate along radial glial fibers. A fraction of cells, however, turned within the intermediate zone and migrated orthogonal to the radial fibers. This orthogonal migration may contribute to the tangential dispersion of clonally related cortical neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉O'Rourke, N A -- Dailey, M E -- Smith, S J -- McConnell, S K -- EY06314/EY/NEI NIH HHS/ -- NS09027/NS/NINDS NIH HHS/ -- NS28587/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1992 Oct 9;258(5080):299-302.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, Stanford University, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1411527" target="_blank"〉PubMed〈/a〉
