The cerebellum of the dogfish, Scyliorhinus canicula: a quantitative study.

This quantitative study on neuron populations of the dogfish cerebellum reveals noticeable differences in cell size and density between its portions. A remarkable result was the large proportion of granule, Golgi and stellate cells as regards to the Purkinje cells, with some values higher than in many mammals. These results indicate that the complexity level of this Selachian cerebellum is not far from cerebella of some primitive mammals.
