(1) For example, multiple sclerosis involves the progressive destruction of the myelin that insulates neural axons.(2) They then manipulated them in the laboratory to turn them into specialised cells that form myelin , the insulating layer than surrounds nerve fibres.(3) They travel to the brain and mount an assault on a substance called myelin , which acts as a protective sheath around nerve fibers.(4) The neurologic symptoms are a result of destruction of myelin , though axons may also be affected.(5) It turns out that the bacterium that causes leprosy directly damages a protective sheathing, made of the protein myelin , around many nerve cells.(6) Their content of myelinated nerve fibers indicates their origin as branches of the pelvic colonic innervation.(7) Numerous myelinated fibers traversing the globus pallidus make it much paler.(8) Some of these white myelinated fiber bundles can be followed downwards through the ventral part of the pons.(9) It also preserved many of the myelinated nerve fibers in treated animals, compared to untreated rats and those that did not receive the triple combination, the researchers found.(10) Next are areas related to memory, then to spatial orientation and to comprehension of language and then we see myelination in language areas.(11) ‘Genes important for myelination also may be important for cognition,’ she notes.(12) Hence, neuronal circuitry and myelination are disrupted.(13) The slow myelination of inhibitory brain circuits might be an obsolete and maladaptive left-over consequence of evolution by natural selection.(14) The incompletely myelinated frontal lobes of children only gradually join the grid of electrical activity that operates the brain.(15) Other innovations in this group of animals include an adaptive immune system similar to that of humans, a closed and pressurized circulatory system, and myelination of the nervous system.
