Injections of 3H-leucine were made in the entopeduncular nucleus or dentate nucleus of the cerebellum in eight cats. The terminal projection zones of both pathways in the thalamus were studied using the sagittal plane and their relationships to one another as well as to cytoarchitectural boundaries of thalamic nuclei were compared. The data indicate that the territories controlled by the two projection systems are almost entirely segregated. The segregation is mainly along the antero-posterior axis as the main pallidal projection zone occupies the medio-ventral VA while the main dentate projection zone lies posterior to it in the VL. Furthermore, the dorsolateral part of the VA not occupied by pallidal projections receives dentate projections. In the VM, both afferent systems terminate in the lateral part of the nucleus with pallidal territory located anteriorly and dentate territory located posteriorly, again without overlap. As the delineations of nuclear subdivisions in the ventral thalamus of the cat have been a subject of some controversy, it is suggested that the boundaries of the VA, VL and VM in the cat thalamus be defined on the basis of basal ganglia and cerebellar projection zones.
对8只猫的内苍白球核或小脑齿状核注射³H-亮氨酸。利用矢状面研究了这两条通路在丘脑的终末投射区，并比较了它们相互之间以及与丘脑核细胞构筑边界的关系。数据表明，两个投射系统所控制的区域几乎完全分离。这种分离主要沿前后轴进行，因为苍白球的主要投射区占据内侧腹侧VA，而齿状核的主要投射区位于VL中其后方。此外，VA未被苍白球投射占据的背外侧部分接受齿状核投射。在VM中，两个传入系统都终止于核的外侧部分，苍白球区域位于前方，齿状核区域位于后方，同样没有重叠。由于猫腹侧丘脑核亚区的划分一直存在一些争议，建议根据基底神经节和小脑投射区来定义猫丘脑的VA、VL和VM边界。
