However, a new study in Nature Metabolism has results that seem to contradict those findings: Researchers noted that marathon ...

Although there are several molecular or morphological differences between nerve fibers in the PNS and CNS, the basic myelin sheath arrangement and the electrophysiological characteristics are ...

Toluidine blue staining. Myelin is stained in blue. The nerve tract is filled with ring-shaped structures, indicating a transverse section of myelinated nerve fibers. (D) Electron microscopy of a ...

( NewsNation) — Running 26.2 miles can do some damage to the brain, according to a recent study, though the impact is temporary and reversible. A group of researchers studied how marathon running ...

Based on the findings previously collected by Bellen and other researchers, Nave and his colleagues hypothesized that myelin, a protective fatty layer that encloses axons (i.e., nerve fibers ...

A fatty white substance known as myelin provides this insulation for your nerve fibers and allows messages from the brain to move quickly and smoothly to other parts of the body. MS causes the ...

In MS, the immune system attacks the protective myelin coating around nerve fibers, disrupting nerve communication and leading to a range of MS symptoms. Myelin helps electrical signals move ...

Nerve fibers of normal adult animals (e.g., 12 months of age) consist of an axon (brown), and a Schwann cell (blue) forming a myelin sheath (black ring) around the axon. Few harmless, non ...

Myelin is a fatty substance that surrounds and insulates nerve fibers in the brain and spinal cord, forming a sheath that facilitates the rapid transmission of electrical signals between neurons.

A new study reveals that inflammation during pregnancy may impair neurodevelopment in infants by reducing CD11c-positive microglia—key immune cells that support brain myelination.

Quantum is partnering with Massachusetts General Hospital on a clinical study to test a PET tracer for monitoring response to treatment in MS.
