[Retinocerebellar relationships in the cat]

In order to study structural changes in the cerebellum the eye balls were enucleated in 6 adult cats. After unilateral and bilateral ablation of the eyes additional nerve fibres were found connecting the retina with the cerebellum. The retino-cerebellar accessary fibres come to the cerebellum mainly via the medial pedicle, solitary degenerated fibres were found in the medial and inferior pedicles of the cerebellum. Retino-cerebellar fibres were detected in the corklike, roof and dentate nuclei of the cerebellum. Retino-cerebellar straight fibres are projected into the white substance around the vermis as well as into the hemispheres of the cerebellum. No reticular-cerebellar fibres were found in the nucleus globosus.
