Six grasscuttters and six hedgehogs were used for the study. They were obtained from Jobavic farm in Ilorin, Nigeria. The animals were euthanised, transcardially perfused with 0.9% normal saline and by 4% paraformaldehyde solution. the brains of the animals were removed and the cerebellum detached, weighed and processed for histological purpose and comparism. the findings of this study show a well organised gyration and sulci in the grasscutter compared to the hedgehog. the brain and cerebellar weights of the grasscutter are comparably larger than that of the hedgehog. However the cerebellar cortices and the histoarchitecture of the two animals were similar with little variations in the cellular layers especially the Purkinje cell layer. The study concludes that that though there are no marked histological differences between the cerebellar cortices in the two animals, the observed complex motor functions in the grasscutter may be explained by the complexities in their cerebellar gyration and sulci.enGrasscutterHedgehogcerebellar corticesHistoarchitecturalNATURAL SCIENCES::Biology::Organism biology::MorphologyArticle
