Hierarchial symmetric atlas of the human cerebellum with 32 regions.

The human cerebellum is activated by a wide variety of cognitive and motor tasks. Previous functional atlases have relied on single task-based or resting-state fMRI datasets. We developed a functional atlas that integrates information from 7 large-scale datasets, outperforming single dataset parcellations. This atlas has three further advantages:

Overall, the new atlas is an important resource for the study of the interdigitated functional organization of the human cerebellum in health and disease.


Hierarchical organisation into 4 domains, 32 regions, and 68 subregionss.

In total, the atlas was trained on data from 111 healthy participants across 417 unique task conditions spanning cognitive, language, social and motor domains. You can explore the parcellation at the three levels of granularity and in its symmetric and asymmetric version in both volume and surface representation in our online cerebellar atlas viewer .

Versions of the Atlas

The atlas is available for download as part of our Cerebellar Atlas Collection. The parcellation is into 4 domains, 32 regions or 68 subregions (symmetric or asymmetric). The three levels make up a nested hierarchical organization. An additional version with 128 regions subdivides the 32 regions spatially into 4 regions (s: superior, i: inferior, t: tertiary, v: vermal). The color scheme reflects the functional similarity of different regions.

Individual Precision Mapping

The substantial inter-individual variability in cerebellar functional organization limits the utility of a group map. Our probabilistic framework allows the user to combine the group atlas with a short localizer scan (10 min) to derive individual functional regions equivalent to 30 min hour of scan data. For more information on how to use the atlas for individual precision mapping for your study, please see our preprint.
