BACKGROUND: The cerebellum is one of the most consistent sites of neuroanatomic
abnormality in autism, yet it is still unclear how such pathology impacts cerebellar function.
In normal subjects, we previously demonstrated with functional magnetic resonance imaging
(fMRI) a dissociation between cerebellar regions involved in attention and those involved in
