There are different opinions. Look at some of the articles in the Attachment.

Thank you for the articles Vladimir. I'll read all of them. I think that the alterations in terms of corticospinal excitability is a phenomenon. On the other hand, we have a long way to see the big picture in terms of behavioral changes. For now, we have difficulty to answer some questions. For example, does tDCS works for fine and gross movements? If yes, should us apply tDCS on M1 to improve/learning fine movements and should us apply tDCS on SMA to gross and more complex movements? We have a challenging way. Regards, Guilherme

Dear Guilherme! I fully agree with your judgments. Transcranial stimulation effects require detailed analysis.

Any studies being done recently for assessing the effectivity of tDCS on fine motor movements Guilherme Lage
