[Cerebellum of birds: quantitative and comparative study of the Purkinje cells (author's transl)]

The quantitative and comparative analysis of the Purkinje cells indicates the higher mean linear density in the anterior lobe, with regard to posterior lobe, in the cerebellum of the dung cook, Gallus gallus. Likewise the mean linear density of the Purkinje cells in that species, was significantly higher than that estimated in the cerebellum of the pigeon, Columba livia. The relationship between these quantitative differences and the type of locomotion, the walk, predominant in the dung cock is discussed.
