用免疫细胞化学方法研究了28周人胎树皮质17区和18区含CALBINDN(CB)及含PARVALBUMIN(PV)神经元的分布.结果发现,17区会CB及台PV神经元的数量均较18区者多得多,而且与18区比较,它们还可见于皮质较浅的层次,使 17/18区交界处明显可辨.结合我们对人类新皮质含CB及含PV神经元的发育研究结果,本实验结果提示,人类视皮质17区神经元的发育和成熟早于18区神经元. The distributions of CALBINDN (CB) and PARVALBUMIN (PV) -containing neurons in zone 17 and zone 18 of human fetal bark at week 28 were studied by immunocytochemistry 18 are much more and they are also found in lighter cortical areas compared with those in 18 so that the junction of 17/18 is clearly discernible.With our study of the development of human neocortical CB-containing and PV-containing neurons As a result, the results of this experiment suggest that the development and maturation of neurons in human visual cortex, area 17, precede neurons in 18 areas.
