这项研究的目的是分析人类听觉皮质中放射状细胞柱的细胞构筑发育，并将这些“个体发育”细胞柱与放射状细胞排列的“成年”模式相关联。在这项细胞结构分析中，大脑取自妊娠9周至出生后3个月的人胎儿和婴儿。用尼氏染色方法对含有Ecoomo和Koskinas的预期听区TC、TB和TA的塑料切片和火棉胶切片进行染色。在最年轻的胎儿(8-13周)，在发育中的皮质板的整个厚度中都有放射状定向细胞柱(1-3个细胞宽的“个体发育”柱)。在下一个发育期(13~26周)，皮质板浅层出现放射状细胞柱，而皮质板深层由于亚板层的形成(13~15周)、苍白带的出现和前膜的发育而呈现出不同的细胞排列。
The aim of this study was to analyse cytoarchitectonic development of radial cell columns in the human auditory cortex and to correlate these ‘ontogenetic’ cell columns with the ‘adult’ pattern of radial cell arrangement. For this cytoarchitectonic analysis, brains were obtained from human fetuses and infants ranging between 9 weeks of gestation and third postnatal month. Plastic and celloidin sections containing prospective auditory areas TC, TB and TA of Economo & Koskinas were stained by Nissl method. In youngest fetuses (8–13 weeks) radially oriented cell columns (1–3 cell wide ‘ontogenetic’ columns) were found in the whole thickness of the developing cortical plate. During the next developmental stage (13–26 weeks of gestation), radial cell columns were present in the superficial part of the cortical plate, while the deep part of the cortical plate showed a variable cell arrangement due to the formation of the subplate layer (13–15 weeks), The appearance of the pale bands, and development of the pros...
