纹状体allidonigral连接研究注入顺行示踪剂到任何联合或感觉运动纹状体在10只猕猴。使用精确的制图方法对结果进行了分析。注射到各个部分的关联纹状体（尾状核和腹内侧壳核）产生的标记的轴突在背内侧和腹侧苍白球区域。这些联合区域占据外侧苍白球的三分之二和内侧苍白球的三分之一。带标记的轴突从感觉运动纹状体（背外侧壳核）被发现在剩余的，中央部分的两个苍白球核。在黑质，吻侧联合纹状体投射内侧网状部，而尾部的部分向外投射。因此，整个网状部和外侧部似乎接受关联纹状体输入。感觉运动区投射到网状部/外侧部的中央部分。得出的结论是，这两个功能的领土仍然分开的两个苍白球核，但在中间的三分之一的黑质重叠。然而，由于其巨大的尺寸，苍白球神经元位于边界的两个领域可能会收到纹状体输入的联想和感觉运动组件以同样的方式黑质神经元。
The striatopallidonigral connection was studied by injecting anterograde tracers into either the associative or the sensorimotor striatum in ten macaques. The results were analyzed using a precise cartographic method. Injections into various parts of the associative striatum (caudate nucleus and ventromedial putamen) produced a labeling of axons in the dorsomedial and ventral pallidal regions. These associative regions occupied two-thirds of the lateral pallidum and one-third of the medial pallidum. Bands of labeled axons from the sensorimotor striatum (dorsolateral putamen) were found in the remaining, central part of the two pallidal nuclei. In the substantia nigra, the rostral associative striatum projected medially to the pars reticulata, while the caudal parts projected laterally. The whole pars reticulata and lateralis thus appeared to receive associative striatal inputs. The sensorimotor striatal territory projected to the central part of the pars reticulata/lateralis. It was concluded that the two functional territories remain separate in the two pallidal nuclei but overlap in the middle third of the substantia nigra. However, due to their great size, the pallidal neurons located at the border of the two territories may receive striatal inputs from both the associative and the sensorimotor components in the same way that nigral neurons do.
