The development of cerebral cortex neurons has been studied in different stages of pre- and postnatal periods of rats. In order to show the neuronal processes, the Golgi-Cox impregnation technique was used. The first neuronal process development was observed in the cranial and caudal poles of the cerebral cortex during the 15th prenatal day and continued spreading from the lateral regions and poles towards the dorsocentral regions of the hemispheres. The cells which showed the first impregnation in the cerebral cortex, were bipolar cells and their bodies were located in the deep regions of the hemisphere wall. Primitive multipolar cells, …

Active oxygen species have been proposed to be involved in the aging process of the brain, therefore alterations in the activities of enzymes involved in the defense system against free radicals and other active species could substantially influence the aging process. This study is planned to determine the brain superoxide dismutase (SOD) and catalase activities which defend the components of brain cells against active oxygen species, in order to evaluate whether they play a role in the aging process. The activities of SOD and catalase were measured in the cerebral cortex and cerebellum of Swiss male albino rats aged either …
