Can't find it right now, but there was also an interesting paper ~7 years ago that showed that myelination occurs more readily if myelination occurs regularly (vs. the first time in a longer timespan). That always stuck with me, as it could potentially mean on a higher level that learning itself is a skill that can and needs to be exercised regularly. I'm wondering if that could also explain the decline in neuroplasticity with age. Would love to hear if anyone knows about some newer research in that area!
