Anatomical and Histological Study of the Cerebellum in cognitive modern birds species (gold-capped parrot)

Abstract

The gold- capped Parrots have large and highly folded cerebellum the latter design is protruded forward. Ten long and large primary folia are found insagittal sections. Some of these folia (i.e. V, VI, IX) are subdivided. The result of microscopic examination indicates that there are an outer long strip of cortexthat corresponding with cerebellum length, and inner white matter (medulla).Three distinct layers are clearly detected in the cortex (i.e. outer molecular layer, middle Purkinje cells layer, and inner molecular, layer). The internal structure of cerebellum is characterized by the great prominence of granular layer especially in the folia summit and the appearance of deep nuclei in the center ofcerebellum.
