对成年金丝雀端脑两个发声控制核——尾侧腹侧上纹状体（HVc）和原纹状体粗核（RA）的连接进行了研究。所采用的方法是辣根过氧化物酶和³H - 腺苷的转运以及退变轴突的银染。有三个核向HVc投射：新纹状体前部的大细胞内侧核（MAN）、新纹状体中部的界面核（NIf）以及间脑的葡萄状核（Uva）。Uva也向NIf投射。NIf和Uva此前未曾被描述过。HVc投射到副嗅叶的X区、RA以及腹侧上纹状体的雪崩区。RA核接收来自HVc和外侧MAN的投射。所有这些投射都是同侧的。在HVc的传入和传出投射中，没有明显的雌雄差异。将辣根过氧化物酶局部注射到RA或HVc后，HVc中的细胞体对该物质的摄取表明，HVc由前后排列的细胞簇组成，它们之间几乎没有横向联系。
Connections of 2 telencephalic vocal control nuclei, the hyperstriatum ventrale, pars caudale (HVc), and robust nucleus of the archistriatum (RA), were investigated in adult canaries. Methods used were transport of horseradish peroxidase and 3H-adenosine and silver staining of degenerating axons. Three nuclei project to HVc: medial nucleus magnocellularis of the anterior neostriatum (MAN), nucleus interfacialis (NIf) of midneostriatum, and nucleus uvaeformis (Uva) of the diecephalon. Uva also projects to NIf. NIf and Uva have not been previously described. HVc projects to area X of lobus parolfactorius, to RA, and to field avalanche of hyperstriatum ventrale. Nucleus RA receives projections from HVc and from lateral MAN. All these projections are ipsilateral. No gross male/female differences were apparent in the projections to and from HVc. Uptake of HRP by cell somata in HVc following localized injections of this substance into RA or HVc suggests that HVc is composed of rostrocaudally organized clusters of cells, with little lateral communication between them.
