Research Abstract |
In this study, we analyzed the effect of prenatal glucocorticoid on the cortical formation, neuronal differentiation and neuronal network. When the primary hippocampal neuron cultured cell was given a corticosterone, caldesmon in the spain decreased it in concentration-dependency through a serum response factor and destabilized the F-actin. As a result of having analyzed neural network formation in the posterior white matter of the glucocorticoid exposed adolescent rat by diffusion tensor imaging, we revealed that an axonal flow became more anisotropic in the glucocorticoid exposure group. As above, we confirmed that the brain development was affected by the prenatal glucocorticoid exposure.
