This phenomenon best illustrates "plasticity".
Plasticity refers to the capacity of the brain to change with learning. Plasticity can likewise be seen in the brains of bilinguals. It would seem that taking in a second dialect is conceivable through useful changes in the cerebrum: the left inferior parietal cortex is bigger in bilingual brains than in monolingual brains.
Plastic changes additionally happen in performers brains contrasted with non-musicians.
