Le cervelet des poissons: variations morphologiques du paleocerebellum en relation avec le développement musculaire et l'activité motrice chez quelques Sélaciens et Téléostéens

In Selacians, cerebellum is made of archicerebellar parts: auricles, cerebellar crest, and a paleocerebellar part: cerebellum's main part. In Teleosts archicerebellum is made of granular eminences, the cerebellar crest, the cerebellar valve and the paleocerebellar, cerebellum's main part. The main part of cerebellum (paleocerebellum), which is the main focus of this note, is a mass, more or less voluminous, formed by a dorsal evagination emanating from the metacoele, totally or partly filled with granular masses.
