To investigate the degree of convergence of corticostriatal inputs from the primary motor cortex (MI) and the supplementary motor area (SMA), we analyzed the extent to which corticostriatal inputs from forelimb representations of these motor-related areas spatially overlap in the macaque monkey. Of particular interest was that corticostriatal input zones from SMA overlapped those from MI of the contralateral hemisphere more extensively than from MI of the ipsilateral hemisphere.
为了研究来自初级运动皮层（MI）和辅助运动区（SMA）的皮质纹状体输入的汇聚程度，我们分析了这些运动相关区域前肢代表区的皮质纹状体输入在猕猴大脑中空间重叠的程度。特别值得关注的是，SMA的皮质纹状体输入区与对侧半球MI的输入区重叠程度，比与同侧半球MI的重叠程度更广泛。
