Small amounts of horseradish peroxidase conjugated with wheat germ were injected in restricted parts of the postarcuate premotor area of the macaque monkey. It was found that regions of this area having different somatotopic representations are richly interconnected among them. This pattern of intra-areal connectivity was not observed in the precentral motor area. It appears therefore that the postarcuate area is organized according to anatomical principles which are different from those of the primary motor cortex.
将少量与小麦胚芽结合的辣根过氧化物酶注射到猕猴弓形后运动前区的特定部位。结果发现，该区域中具有不同躯体定位表征的区域之间相互连接丰富。在中央前运动区未观察到这种区域内连接模式。因此，似乎弓形后区是按照与初级运动皮层不同的解剖学原理组织起来的。
