Oligodendrocytes provide the supplies and work required to remodel myelin. But the ultimate gatekeeper of activity-regulated myelination is, of course, neuronal activity. When coaxed into action, ...

How does our nervous system operate so quickly and efficiently? The answer lies in a membranous structure called myelin. Aa Aa Aa All our activities — eating, walking, talking — are controlled by our ...

New work in mice is revealing how losing insulation on just a few nerve fibers can throw off the timing of brain signals and unravel complex thought. Instead of needing widespread damage, the research ...

Marathon runners experience reversible changes in their brain myelin. These findings indicate that myelin (a substance that surrounds the neurons) exhibits behavior that was previously unknown, and ...

Researchers at Oregon Health & Science University have identified a gene that plays a crucial role in the brain's ability to form the protective layer around nerves known as myelin, potentially ...

Scientists have found that the process of adaptive myelination, which helps the brain learn new skills, can also promote addiction to opioids. Our brains, even in adulthood, continually adapt to what ...

Scientists identify a high-altitude genetic mutation in yaks that produces ATDR, a Vitamin A metabolite that repairs myelin damage in MS and cerebral paralysis.
