Using the anterograde transport of wheat germ agglutinin-horseradish peroxidase in the cat, the projection fields of the spinocerebellar tracts were studied in the horizontal plane of lobules of the anterior lobe. The central cervical nucleus projected to 3 longitudinal areas in zone A and the medial part of zone B. The T4-T7 segments projected to two major longitudinal areas in zones A and B, and small areas in zones C1-D. The L2-L4 segments projected densely to longitudinal areas in zone A and broad band-like areas in zones B-D. The L5 and L6 segments projected mainly to less demarcated areas in apical parts of zones B-D. The findings suggest that the basic pattern of projection proper to each spinocerebellar tract is consistent in all lobules of termination.
利用小麦胚凝集素-辣根过氧化物酶在猫体内的顺行运输,在小脑前叶小叶的水平面研究了脊髓小脑束的投射区域。中央颈核投射到A区的3个纵向区域和B区的内侧部分。胸4-胸7节段投射到A区和B区的两个主要纵向区域以及C1-D区的小区域。腰2-腰4节段密集投射到A区的纵向区域以及B-D区的宽带状区域。腰5和腰6节段主要投射到B-D区顶端界限不太清晰的区域。这些发现表明,每条脊髓小脑束特有的基本投射模式在所有终末小叶中是一致的。
