Autoradiographic demonstration of VIIIth nerve projections in Rana pipiens.
The anterograde transport of radioactive amino acid was used to demonstrate the primary projections of the VIIIth cranial nerve in 5 leopard frogs. Projections were found to be limited to one contiguous termination field ipsilateral to the injected nerve. The most rostral projections were in the marginal cerebellar granular layer; the most caudal projections were slightly posterior to the entry of nerve X. These projections covered the dorsal, ventral, and caudal nuclei of nerve VIII that have been described by others. No projections were found outside this area.
