Living holosteans, comprising 8 species of bowfins and gars, form a small monophyletic group of actinopterygian fishes, which are currently considered as the sister group to the enormously numerous teleosts and have largely been neglected in neuroanatomical studies. We have studied the catecholaminergic (CAergic) systems by means of antibodies against tyrosine hydroxylase (TH) and dopamine (DA) in the brain of representative species of the 3 genera included in the 2 orders of holostean fishes: Amia calva (Amiiformes) and Lepisosteus platyrhincus, Lepisosteus oculatus, and Atractosteus spatula (Lepisosteiformes). Different groups of TH/DA-immunoreactive (ir) cells were observed in the olfactory bulb, subpallium, and preoptic area of the telencephalon. Hypothalamic groups were labeled in the suprachiasmatic nucleus, tuberal (only in A. calva), retrotuberal, and retromamillary areas; specifically, the paraventricular organ showed only DA immunoreactivity. In the diencephalon, TH/DA-ir groups were detected in the prethalamus, posterior tubercle, and pretectum. In the caudal hindbrain, the solitary tract nucleus and area postrema presented TH/DA-ir cell groups, and also the spinal cord and the retina. Only in A. calva, particular CAergic cell groups were observed in the habenula, the mesencephalic tegmentum, and in the locus coeruleus. Following a neuromeric analysis, the comparison of these results with those obtained in other classes of fishes and tetrapods shows many common traits of CAergic systems shared by most vertebrates and in addition highlights unique features of actinopterygian fishes.

荷斯坦鱼类(Actinopterygii / Neopterygii)脑中儿茶酚胺能系统组织的比较分析。

包括8种弓翅鱼和鱼在内的活着的全人类形成了小型的单翅目放线opter鱼类群,这些群目前被视为众多硬骨鱼类的姊妹群,并且在神经解剖学研究中被很大程度上忽略了。我们已经通过在以下2类鱼类中的3种代表性鱼类的代表性物种的大脑中通过酪氨酸羟化酶(TH)和多巴胺(DA)的抗体研究了儿茶酚胺能(CAergic)系统platyrhincus,斜纹夜蛾和白术铲(Lepisosteiformes)。在端脑的嗅球,皮层下和视前区观察到不同种类的TH / DA免疫反应(ir)细胞。下丘脑组标记在结chi上核,结核中(仅在曲霉中),肾后和乳房后区域;具体而言,脑室旁器官仅显示DA免疫反应性。在前脑中,在丘脑前,结节后和前庭中检测到TH / DA-ir组。在尾后脑中,孤立道核和视网膜后区域呈TH / DA-ir细胞群,还有脊髓和视网膜。仅在小曲霉中,在哈贝努拉,中脑被膜和蓝斑中观察到特定的CAergic细胞群。经过神经元分析,将这些结果与其他类别的鱼类和四足动物获得的结果进行比较,显示了大多数脊椎动物共有的CAergic系统的许多共同特征,此外还突出了放线​​翅目鱼类的独特特征。脑室旁器官仅显示DA免疫反应性。在前脑中,在丘脑前,结节后和前庭中检测到TH / DA-ir组。在尾后脑中,孤立道核和视网膜后区域呈TH / DA-ir细胞群,还有脊髓和视网膜。仅在曲霉菌中,在哈贝努拉,中脑被膜和蓝斑中观察到特定的CAergic细胞群。经过神经元分析,将这些结果与其他类别的鱼类和四足动物获得的结果进行比较,显示了大多数脊椎动物共有的CAergic系统的许多共同特征,此外还突出了放线​​翅目鱼类的独特特征。脑室旁器官仅显示DA免疫反应性。在前脑中,在丘脑前,结节后和前庭中检测到TH / DA-ir组。在尾后脑中,孤立道核和视网膜后区域呈TH / DA-ir细胞群,还有脊髓和视网膜。仅在曲霉菌中,在哈贝努拉,中脑被膜和蓝斑中观察到特定的CAergic细胞群。经过神经元分析,将这些结果与其他类别的鱼类和四足动物获得的结果进行比较,显示了大多数脊椎动物共有的CAergic系统的许多共同特征,此外还突出了放线​​翅目鱼类的独特特征。孤立道核和视网膜后区域呈TH / DA-ir细胞群,还有脊髓和视网膜。仅在曲霉菌中,在哈贝努拉,中脑被膜和蓝斑中观察到特定的CAergic细胞群。经过神经元分析,将这些结果与其他类别的鱼类和四足动物获得的结果进行比较,显示了大多数脊椎动物共有的CAergic系统的许多共同特征,此外还突出了放线​​翅目鱼类的独特特征。孤立道核和视网膜后区域呈TH / DA-ir细胞群,还有脊髓和视网膜。仅在曲霉菌中,在哈贝努拉,中脑被膜和蓝斑中观察到特定的CAergic细胞群。经过神经元分析,将这些结果与其他类别的鱼类和四足动物获得的结果进行比较,显示了大多数脊椎动物共有的CAergic系统的许多共同特征,此外还突出了放线​​翅目鱼类的独特特征。
