The organization of the interhemispheric projections from the substantia nigra to the caudate-putamen was examined after [3H]leucine had been injected into the substantia nigra on one side. There was not a strict correspondence between the regions of termination of the crossed and homolateral nigrostriatal projections. Although the leucine predominantly labeled the lateral parts of the ipsilateral caudate-putamen, terminal labeling was also found in the medial and lateral parts of the contralateral caudate-putamen. The crossed nigrostriatal projection terminated in discrete areas of variable size in the contralateral caudate-putamen. The patterns made by the silver granules in the caudate-putamen contralateral to the [3H]leucine injection appeared to be heterogeneous.
在一侧黑质注射[3H]亮氨酸后，研究了从黑质到尾状核-壳核的半球间投射的组织情况。交叉和同侧黑质纹状体投射的终止区域之间没有严格的对应关系。虽然亮氨酸主要标记同侧尾状核-壳核的外侧部分，但在对侧尾状核-壳核的内侧和外侧部分也发现了终末标记。交叉的黑质纹状体投射终止于对侧尾状核-壳核中大小不一的离散区域。与[3H]亮氨酸注射侧相对的尾状核-壳核中银颗粒形成的模式似乎是异质性的。
