Résumé
Although having a relatively homogeneous cytoarchitectonic organization, the cerebellar cortex is a heterogeneous region characterized by different amounts of myelin, iron and protein expression profiles. In this study, we used quantitative T <sub>1</sub> and T <sub>2</sub> * mapping at ultra-high field (7T) MRI to investigate the tissue characteristics of the cerebellar gray matter surface and its layers. Detailed subject-specific surfaces were generated at three different cortical depths and averaged across subjects to create averaged T <sub>1</sub> - and T <sub>2</sub> *-maps on the cerebellar surface. T <sub>1</sub> surfaces showed an alternation of lower and higher T <sub>1</sub> values when going from the median to the lateral part of the cerebellar hemispheres. In addition, longer T <sub>1</sub> values were observed in the more superficial gray matter layers. T <sub>2</sub> *-maps showed a similar longitudinal pattern, but no change related to the cortical depths. These patterns are possibly due to variations in the level of myelination, iron and zebrin protein expression.
