Spinocerebellar projection fields in the horizontal plane of lobules of the cerebellar anterior lobe in the cat: an anterograde wheat germ agglutinin-horseradish peroxidase study.
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.
