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 ...

Devaux and Gow demonstrate how a tight junction protein called claudin 11 makes the neuronal myelin sheath a snug fit. The study will be published in the December 1, 2008 issue of the Journal of Cell ...

Scientists have discovered how damage to the myelin sheath—the insulating layer around nerve fibers—affects brain activity during sleep.

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 ...

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 ...

Myelin degeneration disrupted sleep-related brain rhythms in mice and was linked to altered REM activity in patients with ...

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 ...

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.

Like a string of beads, the cholesterol- and lipid-rich myelin sheaths coat and insulate nerve fibres in order to enable fast and efficient impulse transmission. As we all know, a string of beads can ...

An understanding of the structure and composition of the myelin sheath is essential to understand the pathogenesis of demyelinating diseases such as multiple sclerosis (MS). The presence of citrulline ...

Nerve fibers are surrounded by a myelin sheath. Scientists at the Technical University of Munich (TUM) have now made the first-ever "live" observations of how this protective layer is formed. The team ...
