Abstract

The contour lines of horseradish peroxidase injection sites in the ventrobasal hypothalamus were distorted by the border between arcuate and ventromedial nuclei as well as between arcuate nucleus and median eminence. The dense array of tanycyte processes is assumed to isolate the arcuate nucleus from the neighboring territories by establishing a diffusional barrier surface.

摘要

辣根过氧化物酶在下丘脑腹内侧核注射部位的轮廓线被弓状核与腹内侧核之间以及弓状核与正中隆起之间的边界扭曲。致密排列的伸长细胞突起被认为通过建立一个扩散屏障表面将弓状核与相邻区域隔离开来。
