I have a related story. During a visit to a doctor when I was a kid, the doctor found me unruly, noisy, and over-active. Being a friend of my parents, he flatly and frankly told them, and in front of me, that I "cannot sit still" and suggested they enroll me into a Go classroom, which they promptly did. After a few months I visited him again, and he said, again in everyone's presence, that I was "much better." I was actually not yet mature enough to care or comprehend what it was all about, but I am thankful for having had those lessons. I also daresay that the benefits of taking such lessons would have comparable or perhaps superior effects to these lab-controlled exercises, at least when there is still uncertainty. However, as per the article, the goal, I believe, is self regulation, so at least in my case, the neural changes probably were not focused in the cerebellum.
