Summary
The termination patterns in the cerebellar anterior lobe of one mossy fiber path, the exteroceptive component of the cuneocerebellar tract (E-CCT), and one climbing fiber system, the dorsal spino-olivocerebellar paths (DF-SOCPs), which both relay in the main cuneate nucleus, were compared in the cat. The E-CCT terminates in the ipsilateral half of the anterior lobe in five sagittal zones which overlap five of the eight zones activated from the DFSOCPs. In at least one zone the E-CCT projection has a somatotopical organization which is similar to and overlaps that of the DF-SOCP.
