Break 'myelination' down into sounds: say it out loud and exaggerate the sounds until you can consistently produce them. Myelin is a lipid-rich (fatty) substance that surrounds nerve cell axons (the nervous system's "wires") to insulate them and increase the rate at which electrical impulses (called action potentials) are passed along the axon. MRIs of the brain can look at specific parts of the brain and assess whether the amount of myelin covering the nerves is a normal amount or if there is a decreased amount of myelin visible. mijelinizacija Englesko-hrvatski-rjecnik. 1 The disorder is caused by mutations or rearrangements in the PLP1 gene, located on chromosome Xq22 and encoding myelin proteolipid … Myelination is a process of creating the myelin sheath that surrounds the axons of the nerves, forming an electrically insulating layer (think of the rubber coating that insulates copper wire). This coating enables the electrical impulses between nerve cells to travel back and forth rapidly.
