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.
