Web28 mei 2013 · How Myelination Affects Nerve Impulses. We sometimes refer to our brains as “grey matter” because from the outside, the brain looks mostly grey – that’s what color our neuron cell bodies appear as. But there is also a lot of “white matter” in our brains that fills nearly 50% of our brains. WebDuring infancy, myelination progresses rapidly, with increasing numbers of axons acquiring myelin sheaths. This corresponds with the development of cognitive and motor skills, including language comprehension, speech acquisition, crawling and walking.
