The differences expressed as length of the granular layer in median sections were significant in lobules VIa, VIII, IX and X. The length of the other vermian lobules is generally higher in the former strain. With regard to the volume of the granular layer, the situation is reversed, indicating that the lateral extent and thickness of vermian lobules in Wistar rats (strain Chbb:THOM) is generally larger. These quantitative differences may express differences in cerebellar microcircuitry and fibre connections in the cortex of Wistar and Sprague-Dawley rats.

L. T1 - Regionale Unterschiede der numerischen Purkinje-Zell-Dichte in Kleinhirnen von Albinoratten zweier Stämme N2 - The total number and the number of Purkinje cells per square millimeter of the surface of the cerebellar granular layer were measured in albino rats from two strains: Chbb-THOM-Wist and Han: SPRD. The total number of the Purkinje cells in the cerebellar vermian lobules L land L X with the exception of cells in the lobules VIb + c did not. differ significantly. Statistically significant differences were found between the individuals of the two rat strains and within single lobules of the cerebella concerning the cell density of Purkinje cells per square millimeter surface of the granular layer. The results suggest heterogeneity of the cerebellar cortex between cerebellar lobules and between albino rats derived from different strains.
