The quantitative properties of the cerebellum were assessed by acquiring T₁ and T₂*contrasts at 7T and mapping these onto the cerebellar cortex. T₁ maps showed medial-lateral alternating stripes of different intensities while T₂* values were homogeneously distributed across the lobes. This study showed the heterogeneity of the cerebellar cortex in terms of tissue content, which in part parallels a well-established gene expression pattern.
