In 4 rhesus monkeys wheat germ agglutinin-horseradish peroxidase (WGA-HRP) injections were made in the mesencephalic tegmentum. In 3 cases with injections involving the red nucleus (RN), rubrospinal fibers descended mainly contralaterally to terminate in laminae V, VI and dorsal VII of the spinal cord and in the lateral motoneuronal cell groups at the level of the cervical and lumbosacral enlargements. In all 4 cases the area of the interstitial nucleus of Cajal (INC) was injected, which resulted in labeled interstitiospinal fibers in the medial part of the ipsilateral ventral funiculus of the spinal cord. The results indicate that there is no major qualitative difference between the mesencephalic (RN and INC) and motor cortical projections to the spinal cord.
在4只恒河猴中，将小麦胚凝集素-辣根过氧化物酶（WGA-HRP）注入中脑被盖。在3例注射涉及红核（RN）的病例中，红核脊髓纤维主要向对侧下行，终止于脊髓的V层、VI层和背侧VII层以及颈膨大与腰骶膨大水平的外侧运动神经元细胞群。在所有4例中，均对 Cajal间质核（INC）区域进行了注射，结果在脊髓同侧腹侧索的内侧部分出现了标记的间质脊髓纤维。结果表明，中脑（红核和 Cajal间质核）与运动皮层向脊髓的投射在质量上没有重大差异。
