The vermal projection of spinocerebellar tracts arising from lower cervical segments in the cat: an anterograde WGA-HRP study.
Following injections of WGA-HRP into lower cervical segments, the distribution of anterograde labeled terminals of spinocerebellar fibers was examined in the vermal cortex of the cat. The labeled terminals were seen in sublobules Ib to VIc, VIIb, VIIIa and VIIIb, and lobule IX. They were present mainly in the medial part of the vermis, at most within 2.0 mm from the midline, and in the apical to middle parts of these lobules in the apicobasal extent. The present study demonstrates that the neuronal groups in the medial part of lamina VI and the central part of lamina VII of lower cervical segments project to the vermis of the caudal lobules of the anterior lobe and the rostral lobules of the posterior lobe.
