| Abstract: | Objective To explore the age-related changes of myelin sheath microstructure in the frontal region of corpus callosum.Methods Myelin sheath microstructure in the frontal region of corpus callosum of young(6 months old),middle-aged(18 months old) and old-aged female(27 months old) Long-Evans rats were studied by electron microscope and unbiased stereological techniques.Results There was no significant change in mean diameter of axons(inner diameter),mean diameter of myelinated fibers(external diameter),mean ... |
| Keywords: | myelinated nerve fibers myelin sheaths frontal region of corpus callosum stereology |
