Abstract
Previous studies have documented that motor training improves performance on motor skill tasks and related this to altered functional brain
activity in cerebellum, striatum, and frontal motor cortical areas. Mental training can also improve the performance on motor tasks, but the neural
basis of such facilitation is unclear. The purpose of the present study was to identify neural correlates of training-related changes on a finger-tapping
task. Subjects were scanned twice, 1 week apart, with fMRI while they performed two finger-tapping sequences with the left hand. In-between
scans, they practiced daily on one of the sequences. Half of the participants received motor training and the other half received mental training
(motor imagery). Both training procedures led to significant increases in tapping performance. This was seen for both the trained and the untrained
sequence (non-specific effect), although the g
