Although LTP is one of the main ways that neurons learn, scientists have identified other mechanisms. One of the most intriguing mechanisms that have been recently discovered, is "activity-dependent myelination," which involves preferential myelination of axons that are active during learning.
Although we don't fully understand this process, this suggests that _______ in the central nervous system are likely to play some role in learning, as well.

a) Astrocytes
b) Microglia
c) Oligodendrocytes
d) Schwann Cells
