以脑室坐标为参照，建立了猕猴苍白球和纹状体横切面图谱。通过矢状和水平重建研究了纹状体-苍白球复合体的三维几何结构。我们用放射自显影和文献资料分析了纹状体内皮质轴突的分布。我们可以区分两个纹状体区域：一个是躯体定位排列的感觉运动区域，延伸到壳核的主要部分;另一个是联合区域，包括尾状核和壳核的前内侧和后内侧。使用Golgi、Perls和Fink-Heimer技术研究纹状体-苍白球-黑质束。该束被描述为四个部分：苍白球前（再分为尾苍白球和putamino-pallidal子部分），transallidal，苍白球黑质和黑质。追踪尾状核（联合区）和壳状核（主要是感觉运动区）之间的界限表明，这两个组成部分在苍白球中的大小大致相同。将这些数据与Yelnik等（1984）分析的大苍白球神经元树突分支的几何形状和方向进行比较。每个苍白球树突盘能够接受来自纹状体广泛区域的轴突。这导致了收敛苍白球神经元的纹状体轴突从不同的纹状体体视带和从感觉运动和联想的领土。这表明苍白球可能具有整合作用。
An atlas of transverse sections of the globus pallidus and striatum was established in macaque with reference to ventricular coordinates. The three‐dimensional geometry of the striato‐pallidal complex was investigated by means of sagittal and horizontal reconstructions. Both a personal case studied with autoradiography and data from literature were used to analyze the distribution of cortical axons into the striatum. One may distinguish two striatal territories: one, somatotopically arranged, sensorimotor territory extending over the major part of the putamen; and the other, an associative territory, comprising the caudate nucleus and antero‐medial and postero‐inferior parts of the putamen. The striato‐pallido‐nigral bundle was studied using Golgi, Perls, and Fink‐Heimer techniques. The bundle is described in four parts: prepallidal (subdivided into caudato‐pallidal and putamino‐pallidal subparts), transpallidal, pallido‐nigral, and nigral. The tracing of the limit between the caudate (associative) and putaminal (essentially sensorimotor) territories shows that the two components are of roughly the same size in the pallidum. The data were compared with geometry and orientation of the dendritic arborizatons of large pallidal neurons analyzed in Yelnik et al. (1984). Each pallidal dendritic disc is able to receive axons from a wide region of the striatum. This leads to a convergence on pallidal neurons of striatal axons from different striatal somatotopic strips and from the sensorimotor and associative territories. This is an indication that the globus pallidus may have an integrative role.
