The efferent projections of the suprachiasmatic nucleus of the hypothalamus (SCN) have been investigated by the use of the anterograde autoradiographic technique. The majority of the fiber connections from SCN are to hypothalamic nuclei. The dorsal and periventricular parvocellular divisions of the paraventricular nucleus (PVN) and the medial part of the dorsomedial hypothalamic nucleus receive dense fiber projections. Also, fibers about the medial parvocellular division of PVN. Many descending fibers course into the retrochiasmatic area and pass to the ventral and medial borders of the ventromedial hypothalamic nucleus, as well as through the central zone of this nucleus. A few fibers at the lateral border of the ventromedial hypothalamic nucleus sweep dorsomedially into the posterior hypothalamic area and midbrain central gray. The major extrahypothalamic projection is to the periventricular thalamic nucleus.
利用顺行性放射自显影技术对下丘脑视交叉上核（SCN）的传出投射进行了研究。来自SCN的大多数纤维连接至下丘脑核团。室旁核（PVN）的背侧和室周小细胞部以及下丘脑背内侧核的内侧部分接受密集的纤维投射。此外，还有纤维围绕PVN的内侧小细胞部。许多下行纤维进入视交叉后区，并通向腹内侧下丘脑核的腹侧和内侧边界，以及穿过该核的中央区。腹内侧下丘脑核外侧边界的少数纤维向背内侧延伸至下丘脑后区和中脑中央灰质。主要的下丘脑外投射是至室周丘脑核。
