Not sure... to my knowledge, there is limited evidence that myelination is directly related to habit formation or motor learning. Only very recently, brain imaging studies have shown changes in white matter associated with learning a task, but it is not clear whether this reflects myelination. The idea that myelin deposition might affect cognition is speculative (although interesting and plausible, in my opinion). Plasticity refers to changes in the connections between neurons, it is likely that one of the ways behaviors are consolidated and become 'habits' is through strengthening and weakening of specific connections between nerve cells.
