Using the retrograde transport of horseradish peroxidase-labeled wheat germ agglutinin, a direct projection from the globus pallidus to the caudate nucleus and putamen was shown in the cat. The retrograde transport of the fluorescent dye Granular blue was used in a squirrel monkey to demonstrate a similar projection from the external pallidal segment to the putamen. No cell-labeling occurs in the cat's entopeduncular nucleus or the monkey's internal pallidal segment. In the cat, the pallidostriatal neurons are found in all parts of the globus pallidus and project throughout the striatum. However, the pallidostriatal projection is topographically organized such that it reciprocates the topography of the striatopallidal projection.
利用辣根过氧化物酶标记的小麦胚凝集素的逆行运输，在猫身上显示了从苍白球到尾状核和壳核的直接投射。在松鼠猴中使用荧光染料颗粒蓝的逆行运输来证明从苍白球外部节段到壳核的类似投射。在猫的内苍白球核或猴的苍白球内部节段中未出现细胞标记。在猫中，苍白球纹状体神经元存在于苍白球的所有部位，并投射到整个纹状体。然而，苍白球纹状体投射在地形上是有组织的，从而与纹状体苍白球投射的地形相对应。
