The hypothalamo-hypophysial neurosecretory (HN) complex of Trichogaster fasciatus is described with the help of in situ staining technique and tissue sections. The neurons of the nucleus preopticus (NPO) give rise to fine neurosecretory axons which form the left and right main tracts. The bulk of the tracts come laterally and enter the middle portion of the neurohypophysis. However, some of them spread out and penetrate the rostral neurohypophysis as well. Hypophysial artery contributes to the formation of primary capillary plexus (PCP) which extends from the subterminal region to the extremity of the anterior neurohypophysis. Structurally, the subterminal region and the anterior neurphoyophysis can be compared to the median eminence (ME) of tetrapods as it is differentiated into ependymal, fibrous and reticular layers. Also, these areas have aboundant neurosecretory and silver positive axons suggesting the possibility of direct transmission of neurohormones into the blood.
借助原位染色技术和组织切片对条纹毛足鲈的下丘脑 - 垂体神经分泌（HN）复合体进行了描述。视前核（NPO）的神经元发出细小的神经分泌轴突，形成左右主束。大部分束从侧面进入神经垂体中部。然而，其中一些也会散开并穿透神经垂体的前端。垂体动脉有助于形成从终末下区域延伸至神经垂体前端的初级毛细血管丛（PCP）。在结构上，终末下区域和神经垂体前端可与四足动物的正中隆起（ME）相比较，因为它可分为室管膜层、纤维层和网状层。此外，这些区域有丰富的神经分泌和银阳性轴突，表明神经激素可能直接进入血液。
