Abstract

The topographical localization and some cytochemical characteristics of groups of perivascular neurons in the hypothalamus and in the optic chiasma have been studied. In the anterior hypothalamic area there are neuronal groups located around the blood vessels which penetrate the optic chiasma still associated with neurons. These perivascular neurons show some characteristics similar to those observed in neurosecretory hypothalamic neurons, but differ from them in that they show a greater intensity of thiaminopyrophosphatase and nucleoside-diphosphataseactivities. It is suggested that these neuronal groups may constitute a special hypothalamochiasmatic-perviscular-neurosecretory system (H. Ch. P. N. S.).

摘要

对下丘脑和视交叉处血管周围神经元群的地形定位及一些细胞化学特征进行了研究。在下丘脑前部区域，存在围绕穿透视交叉且仍与神经元相连的血管分布的神经元群。这些血管周围神经元呈现出一些与下丘脑神经分泌神经元中观察到的特征相似的特点，但不同之处在于它们表现出更高强度的硫胺素焦磷酸酶和核苷二磷酸酶活性。有人提出，这些神经元群可能构成一个特殊的下丘脑 - 视交叉 - 血管周围 - 神经分泌系统（H.Ch.P.N.S.）。
