本文研究了罗非鱼和侏儒的末梢神经节(TN)的传入来源。对TN-GGL及其周围嗅球进行示踪后，在端脑背部后部(DP)、端脑部腹侧和腹侧上区(Vv和Vs)、Prasada Rao和Finger的被盖嗅核(1984)和蓝斑均有逆标神经元。对侧嗅球内可见标记细胞，TN-GGL内可见终末。然后进行示踪剂注入实验，以确定TN-GGL的可能来源。示踪剂应用于中脑盖-嗅核，标记的终末在TN-GGL丰富，而在嗅球本身的标记很少。逆行标记神经元分布于丘脑腹内侧核、后连合核、顶盖前背侧区、三叉神经感觉核和网状结构上内侧核。示踪剂主要应用于嗅球内的DP或VS/VV标记终末。然而，TN-GGL的终末是从标记轴突向嗅球供应的。对蓝斑的示踪剂注射只标记了TN-GGL周围的几个纤维。这些结果表明，TN-GGL接受来自被盖-嗅核的躯体感觉和视觉输入，以及来自接受次级嗅觉投射的嗅球和端脑亚区的嗅觉输入。蓝斑也可向TN-GGL发出纤维。J.Comp.神经。428：355-375,2000。©2000 Wiley-Liss Inc.
Afferent sources to the ganglion (ggl) of the terminal nerve (TN) were studied in percomorph teleosts the tilapia and dwarf gourami. After tracer applications to the TN‐ggl and the surrounding bulbus olfactorius, retrogradely labeled neurons were present in the area dorsalis telencephali pars posterior (Dp), area ventralis telencephali pars ventralis et supracommissuralis (Vv and Vs), nucleus tegmento‐olfactorius of Prasada Rao and Finger ( 1984 ), and locus coeruleus. In the contralateral bulbus olfactorius labeled cells were observed, and terminals were seen in the TN‐ggl. Tracer injection experiments to the possible sources of origin to the TN‐ggl were then performed. Tracer applications to the nucleus tegmento‐olfactorius labeled abundant terminals in the TN‐ggl but labeled very few in the bulbus olfactorius proper. Retrogradely labeled neurons were present in the nucleus ventromedialis thalami, nucleus commissurae posterioris, area pretectalis pars dorsalis et ventralis, nucleus sensorius nervi trigemini, and formatio reticularis pars superius et medius. Tracer applications to the Dp or Vs/Vv labeled terminals mainly in the bulbus olfactorius proper. However, terminals to the TN‐ggl were supplied from labeled axons on their way to the bulbus olfactorius. Tracer injections to the locus coeruleus labeled only a few fibers around the TN‐ggl. These results suggest that the TN‐ggl receives somatosensory and visual inputs from the nucleus tegmento‐olfactorius and olfactory inputs from the bulbus olfactorius and telencephalic subdivisions, which receive secondary olfactory projections. The locus coeruleus may also send fibers to the TN‐ggl. J. Comp. Neurol. 428:355–375, 2000. © 2000 Wiley‐Liss, Inc.
