We investigated in 45 healthy subjects (HC), the structural changes of the gray matter (GM) and white matter (WM) associated with manual dexterity training, with and without musical cue. All subjects underwent magnetic resonance imaging at baseline and after 2 weeks. Diffusivity parameters in the WM skeleton did not change after training, while a musical stimulation during motor training improved motor performance and influenced structural plasticity of the GM. The complexity of the task was associated with more pronounced changes of GM structure.
