Abstract

The development of the human cochlear nucleus was studied in serial sections of the brain of 12 fetuses at 12-40 weeks of gestation, an infant at 2 months of age and an adult of 63 years using an electronic planimeter with a computer. Morphometric analysis of the development of the ventral cochlear nucleus showed that its development accelerates after 18 weeks of gestation in terms of columnar volume, columnar length, neuronal number and neuronal size.

摘要

利用带有计算机的电子求积仪，对12例妊娠12 - 40周的胎儿、1例2个月大的婴儿以及1例63岁成年人的大脑连续切片进行研究，以观察人类耳蜗核的发育情况。对蜗腹侧核发育的形态计量学分析表明，就柱状体积、柱状长度、神经元数量和神经元大小而言，其发育在妊娠18周后加速。
