abstract = {The cerebellum plays important roles in motor, cognitive,
and emotional behaviors. Previous cerebellar
coordinate-based meta-analyses and mappings have attributed
different behaviors to cerebellar subareas, but an accurate
behavioral topography is lacking. Here, we show
overrepresentation of superior activation foci, which may be
exacerbated by historical cerebellar neglect. Unequal foci
distributions render the null hypothesis of standard
activation likelihood estimation unsuitable. Our new method,
cerebellum-specific activation-likelihood estimation
(C-SALE), finds behavioral convergence beyond baseline
activation rates. It does this by testing experimental foci
versus null models sampled from a data-driven, biased
probability distribution of finding foci at any cerebellar
location. Cerebellar mappings were made across five BrainMap
task domains and thirty-five subdomains, illustrating
improved specificity of the new method. Twelve of forty
(sub)domains reached convergence in specific cerebellar
subregions, supporting dual motor representations and
placing cognition in posterior-lateral regions. Repeated
subsampling revealed that whereas action, language and
working memory were relatively stable, other behaviors
produced unstable meta-analytic maps. Lastly, meta-analytic
connectivity modeling in the same debiased framework was
used to reveal coactivation networks of cerebellar
behavioral clusters. In sum, we created a new method for
cerebellar meta-analysis that accounts for data biases and
can be flexibly adapted to any part of the brain. Our
findings provide a refined understanding of cerebellar
involvement in human behaviors, highlighting regions for
future investigation in both basic and clinical
applications.},
