[Anatomical identification of the vestibulo-olivary and cerebello-olivary projections in the cat].

Injections of horseradish peroxidase were made into different parts of the inferior olive in the Cat. It is shown that the vestibular nucleus Z and, to a lesser extent, the nucleus f send off fibres to the ipsilateral medial accessory olive. The ventral part of the nuclei inter-positus and dentatus send off fibres to the ventrolateral outgrowth of the opposite side.
