Specific motor cortex and cerebellar regions control and learn finger motions
the verdict
SUPPORTED
the evidence backs this
confidence 95/100
Neuroimaging and anatomical tracing studies confirm that specific subregions within the primary motor cortex and the cerebellum work in concert to control and adapt sequential finger and limb motions.
