Abstract

Microiontophoresis of horseradish peroxidase (20%) into the median eminence of the rat has allowed visualization of perikarya and axon projections of the tuberoinfundibular system after retrograde transport. Cells projecting to the median eminence were found in the periventricular regions of the hypothalamus and were particularly pronounced in dorsal portions of the rostral arcuate nucleus, the medial division of the paraventricular nucleus, and within the anterior periventricular nucleus. Labeling of perikarya within the ventromedial nucleus was rarely found. No labeling by HRP was found within cells of the dorsomedial, anterior, suprachiasmatic, preoptic, lateral hypothalamic nuclei or within the septal and amygdaloid nuclei. Axons from identifiably cells were located within the periventricular neuropil and contained within the baso-lateral portions of the hypothalamic-hypophysial tract.

摘要

将辣根过氧化物酶（20%）微量离子导入大鼠正中隆起后，经逆行运输可观察到结节漏斗系统的胞体和轴突投射。投射到正中隆起的细胞在下丘脑室周区域被发现，在 Rostral 弓状核背侧部分、室旁核内侧部和室周前核内尤为明显。腹内侧核内的胞体很少被标记。在背内侧、前、视交叉上、视前、下丘脑外侧核的细胞内或隔核和杏仁核内未发现 HRP 标记。来自可识别细胞的轴突位于室周神经毡内，并包含在下丘脑 - 垂体束的基底外侧部分。
