Human Motor Cortex First Lamina and Gray Matter Special Astrocytes: Development and Cytoarchitecture

摘要: During the development of mammalian cerebral cortex, gliogenesis different glial cell types parallel evolution its various compartments. Each basic type evolves at specific time, occupies a compartment, and develops morphological functional features. The following are recognized in developing cortex: radial glia cells, white matter fibrous astrocytes oligodendrocytes, subependymal polymorphous astrocytes, first lamina special gray protoplasmic astrocytes. developmental history each is characteristic occurs time. histories morphologic features most cells have been well documented (Rakic 1972, 1988; Marin-Padilla 1995). However, late both less documented. First needed for maintenance cortex expanding external limiting membrane (EGLM) necessary neuronal vascular maturations (Marin-Padilla
