Abstract

Purkinje cell numbers, densities and arrangement in space were studied by quantitative histology in the cerebella of adult cats. Calculated for the living state the density of the Purkinje cells was 373/sq.mm in entire folia (lobus paramedianus); the density in flattened parts of these folia was 384/sq.mm. The mean density calculated for the total living cerebellum was 330/sq.mm. The total number of Purkinje cells was 1.2-1.3 million. On the basis of the known general principles of shape and arrangement in this study a new space arrangement model is suggested. Purkinje cell bodies are arranged in rows deviating by 11° from the transverse plane of the folium, and neighbouring cells are placed in a rhomboid pattern. In reality certain distortions of this pattern occur, in consequence of a flexibility in the relations of cell bodies to dendritic trees, but the essential correctness of the model can be proved statistically by distance measurements of Purkinje cells in randomly and in geometrically directions.
