For a long time, it has been assumed that brain plasticity peaks at young age and then gradually decreases as one gets older. Interestingly, thanks to tremendous advances in medical imaging techniques for assessment of brain structure and function, mounting evidence for lifelong brain plasticity has been generated over the past years. In the context of practice-induced task learning, a key question
