视上核是丘脑下部最引人注目的核团之一。自 Megnert 1872年对它进行描述以来,不少作者在临床、生理、病理、药理、形态以及形态与功能间的关系等方面进行了大量的工作。随着免疫组化、放射自显影术的发展,对视上核神经元所产生激素的性质、定位也积累了丰富的资料。但有关视上核近似昼夜 The supraoptic nucleus is one of the most striking nuclei in the lower part of the hypothalamus. Since Megnert described it in 1872, many authors have done a great deal of work in clinical, physiology, pathology, pharmacology, morphology and the relationship between morphology and function. With the development of immunohistochemistry and autoradiography, a wealth of information has been accumulated on the nature and location of hormones produced by supraoptic nucleus neurons. But as the last day around the nucleus
