Age- and task-dependent effects of cerebellar tDCS on manual dexterity and motor learning-A preliminary study.

Objectives: The role of the cerebellum in motor learning of dexterous control and interaction with aging remains incompletely understood. We compared the effect of age and cerebellar transcranial direct current stimulation (CRB-tDCS) on motor learning in two different manual dexterity tasks, visuomotor force control vs. effector selection (independent finger movements).
