人胚胎视皮质发育中神经元数密度测量分析
Analysis on the Neuronal Numberical Density Changes in Fetal Visual Cortex during Normal Development
摘要
选取胎龄１２～４０周流产胎儿，对其视皮质进行形态学观察及神经元数密度进行测量分析。结果发现，胎儿视皮质在发育过程中神经元的数密度总的呈现下降趋势，这可能是在发育的一定时期。
The visual cortex of 14 human fetus(12～40weeks from dilatation or curettage and abortion) were studied by stereology analysis and ultrastructure analysis.The results showed that the neuronal numberical densities of each layer of visual cerebral cortex tended to decrease with fetal age.This may mean that the number of neuron were comparatively steady and nearon apoptosis existed.
