title: The organization of the olivocerebellar projection in the chicken.
abstract: The olivocerebellar pathway in the chicken was studied, using the horseradish peroxidase retrograde tracing technique. The inferior olivary nuclear complex (IOC) of the chicken comprises a dorsal and a ventral lamella and projects to the contralateral cerebellar hemisphere. In this paper the organization of the olivocerebellar pathways in the chicken is compared with the mammalian olivocerebellar pathway. The present results, taken in conjunction with data on the embryogenesis of the rat IOC, suggest that the avian dorsal lamella represents, from lateral to medial, the dorsal olivary nucleus, the principal olivary nucleus, and the rostral and a small part of the caudal medial nucleus (MO) of mammals, while the ventral lamella represents a larger part of the caudal MO of mammals.
