title: Termination in overlapping sagittal zones in cerebellar anterior lobe of mossy and climbing fiber paths activated from dorsal funiculus.
abstract: 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 DF-SOCPs. In at least one zone the E-CCT projection has a somatotopical organization which is similar to and overlaps that of the DF-SOCP.
