| Abstract: | 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. |
