For the experimental group, right hemispheric VIII had a stronger functional connectivity with left hemispheric IV-V, cerebellar vermal IX, left middle cingulate gyrus and right hippocampus after training. Taken together, these findings suggested that motor skill learning, at least learning to play badminton in adulthood, reduces resting-state activity in different sub-regions in the cerebellum but increases functional connectivity between sub-regions of the cerebellum as well as between sub-regions of the cerebellum and cerebral cortices (e.g., middle cingulate cortex and hippocampus).
