用戊二醛结合的多巴胺抗血清研究了鸽尾部端脑的多巴胺能神经支配。结果发现，DA样纤维分布于古纹状体和背侧弓状核内，呈密集的纤维网络分布，而前脑尾侧的大部分由多巴胺能轴突支配，这些轴突像篮子一样盘绕在未标记的神经元周围。在篮型神经支配结构中，新纹状体尾侧区(NCL)的多巴胺能纤维密度较高。向NCL逆行注射示踪剂，发现有来自被盖腹侧区(AVT)和中脑被盖脚桥致密部(TPC)的传入。由于在AVT和TPC可检测到大量的DA样包，推测这两个结构构成了NCL的多巴胺能神经支配的主要来源。以前的研究表明，NCL代表着一种相当于哺乳动物前额叶皮质的鸟类。目前的结果揭示了一种类似于中皮质-前额叶系统的组织结构，因此将加强这一假说。
The dopaminergic (DA) innervation of the caudal telencephalon of the pigeon was investigated with an antiserum against glutaraldehylde-conjugated dopamine. It was found that the DA-like fibers were distributed within the Paleostriatum augmentatum and the dorsal Archistriatum in a dense meshwork of fibers, while most of the remaining part of the caudal forebrain was innervated by dopaminergic axons which were coiled up like baskets around unlabelled neurons. Within the basket-type innervated structures, the Neostriatum caudolaterale (Ncl) could be distinguished by the high density of its dopaminergic fibers. Retrograde tracer injections into Ncl revealed afferents from the Area ventralis tegmentalis (AVT) and the n. tegmenti pedunculo-pontinus pars compacta (TPc). Since large numbers of DA-like perikarya could be detected in AVT and TPc, it is supposed that these two structures constitute the main source of the dopaminergic innervation of the Ncl. Previous studies had suggested that the Ncl represents an avian equivalent to the mammalian prefrontal cortex. The present results reveal an organization similar to that of the mesocortico-prefrontal system and would thus strengthen this hypothesis.
