Thin myelin sheaths as the hallmark of remyelination persist over time and preserve axon function. PNAS , October 2017 DOI: 10.1073/pnas.1714183114 Cite This Page : ...

While comparing neurons and transistors is a convenient metaphor (and not completely out of left field), the brain is ...

New research reveals that Alzheimer's disease may impair nerve function not by reducing myelin, but by altering the proteins ...

A new study reveals that neural stem cell grafts can generate new myelin in the central nervous system, offering hope for ...

The myelin sheath surrounding the axons, ... For the complex network of the central nervous system to function properly, the speed of the connections is not the only consideration.

A team of researchers from the University of Wisconsin-Madison reports that in long-lived animals, renewed but thin myelin sheaths are enough to restore the impaired nervous system and can do so ...

The new findings confirm that the gold standard for evaluating remyelination is the long-term persistence of thin myelin sheaths, which support nerve fiber function and survival, Duncan notes. The ...

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 ...

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 ...

With the insights gained, the researchers were able to regenerate damaged myelin sheaths in mice by treating them with the active substance theophylline, thereby restoring their nerve cell function.

Myelin is composed mainly of lipids, and recent animal studies have suggested that in times of energy shortage, the body might tap into these lipid-rich structures to support brain function.

The purpose of the study, says Duncan, was to confirm that thin myelin sheaths persisted and supported normal neurologic function. To expand on the results, Duncan also looked at a condition in cats, ...
