The distribution of serotonin-immunoreactive (5-HTi) neurons was determined by the peroxidase-antiperoxidase technique. 5-HT-immunoreactive nerve cells (or perikarya) occurred in the diencephalic nucleus ventromedialis (nvm), in the so-called pre-pacemaker nucleus (ppm), in a laterally located (unnamed) nucleus (G1), in the nucleus posterior periventricularis (nppv), the nucleus recessus lateralis (nrl) and the nucleus recessus posterior (nrp). 5-HT-immunoreactivity could be localized in the pars intermedia and the proximal pars distalis of the pituitary gland. Large 5-HTi perikarya were found in the lamina VI of the mesencephalic torus semicircularis (ts). Intensely immunostained 5-HTi perikarya occurred in the raphe region. 5-HT-immunoreactivity was also located in the medullary pacemaker nucleus of the specialized electric organ (pm). Only a few 5-HTi fibres were observed in the telencephalon. Ventral to the 3rd ventricle of the diencephalon between the caudal hypothalamic nuclei most of these were fibre bundles dorsal to the nuc. recessus lateralis. Some 5-HTi fibres traversed the pituitary stalk to the proximal pars distalis of the pituitary gland. Scattered 5-HTi fibres were seen in the torus semicircularis, lobus inferior (li) and cerebellum, while more fibres appeared in the medulla oblongata (mo) and below the pacemaker nucleus. The results are compared to those in other fish.
采用过氧化物酶 - 抗过氧化物酶技术确定了5 - 羟色胺免疫反应性（5 - HTi）神经元的分布。5 - HT免疫反应性神经细胞（或胞体）出现在间脑腹内侧核（nvm）、所谓的前起搏器核（ppm）、外侧的一个未命名核（G1）、室周后核（nppv）、外侧隐窝核（nrl）和后隐窝核（nrp）中。5 - HT免疫反应性可定位于垂体中间部和远侧部近端。在中脑半环形隆起（ts）的VI层发现了大型5 - HTi胞体。在中缝区域出现了免疫染色强烈的5 - HTi胞体。5 - HT免疫反应性也位于特殊电器官的延髓起搏器核（pm）中。在端脑中仅观察到少数5 - HTi纤维。在间脑第三脑室腹侧，在下丘脑尾侧核之间，其中大部分是位于外侧隐窝核背侧的纤维束。一些5 - HTi纤维穿过垂体柄到达垂体远侧部近端。在半环形隆起、下叶（li）和小脑中可见散在的5 - HTi纤维，而在延髓（mo）和起搏器核下方出现了更多纤维。将这些结果与其他鱼类的结果进行了比较。
