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.

Morphological and histological aspects on the cerebrum of gold- capped parrot was studied to describe the cerebrum regions which classify and named acording to the new standard nomenclature of the international consortium of avian neuroscientists.The results of morphological aspects (the gross anatomy) revealed that the cerebrum was the largest and the dominant part of the brain, the surface of eachcerebral hemisphere was smooth and without gyri and sulci. The wulst was found as a bulge on the dorsum of each hemisphere, it was massive. The lateralborder of the wulst was demarcated by vallecula groove.The results of histological aspects indicated the presence of two regions: the dorsal (pallial), and the basal (striatal and pallidal) regions. The dorsal ventricular ridge (DVR) was the best developed representing the gray matter.
