Abstract
Using light microscopy, we performed morphometric analysis of various cell populations of brain solitary tract nuclei at various stages of ontogenesis in rats. Sex-related dimorphism of development was observed in eight neuronal populations. Sex-related differences in the structure of these neurons persist in adult rats. The data obtained suggest that solitary tract nuclei participate in brain sexual differentiation.
摘要
利用光学显微镜，我们对大鼠个体发育各阶段脑孤束核的不同细胞群体进行了形态计量分析。在八个神经元群体中观察到了与性别相关的发育二态性。这些神经元结构上的性别相关差异在成年大鼠中持续存在。所获得的数据表明，孤束核参与了脑的性别分化。
