In the central nervous system of humans and all other mammals, a vital insulating sheath composed of lipids and proteins around nerve fibers helps speed the electrical signals or nerve impulses that ...

The myelin sheath is a protective covering that surrounds fibers called axons, which are the long thin projections that extend from the main body of a nerve cell or neuron. This sheath is composed of ...

Researchers from the F.M. Kirby Neurobiology Center in the US have discovered a new approach to restore myelin sheaths, the fatty substance that surrounds nerve cells. The findings may be able to aid ...

New research shows early Multiple Sclerosis brain damage is dynamic and reversible. Myelin swellings can shrink and disappear based on nerve activity.

The disruption of axons—the thread-like part of nerve cells that transmits electrical signals—is associated with Alzheimer’s disease. One way axonal function may be hindered is through damage to the ...

In the central nervous system of humans and all other mammals, a vital insulating sheath composed of lipids and proteins around nerve fibers helps speed the electrical signals or nerve impulses that ...

Nerve fibers are surrounded by a myelin sheath. Scientists have now made the first-ever 'live' observations of how this protective layer is formed. Nerve fibers are surrounded by a myelin sheath.

Bazedoxifene, a drug that alters the activity of the sex hormone estrogen, failed to promote myelin repair in women with MS, ...

Multiple sclerosis (MS) is a serious neurological disease that usually causes permanent disability. Approximately 2.9 million people are affected worldwide, 240,000 in Germany alone. The exact cause ...

In long-lived animals, renewed but thin myelin sheaths are enough to restore the impaired nervous system and can do so for years after the onset of disease, scientists have discovered. In the central ...
