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 ...

According to the Deutsche Multiple Sklerose Gesellschaft (German Multiple Sclerosis Society), around 200,000 people in Germany suffer from multiple sclerosis (MS) - a serious neurological condition ...

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.

Some of the myelin sheaths in the cerebellum of normal adult toads exhibit extensive evaginations of their full thickness. These redundant flaps of myelin are collapsed; i.e., they contain no axon and ...

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 ...

A research team led by neurobiologist Professor Claire Jacob has identified an important mechanism that can be used to control the restoration of myelin sheaths following traumatic injury and in ...

The paper K.M. Young et al., “Oligodendrocyte dynamics in the healthy adult CNS: evidence for myelin remodeling,” Neuron, 77:873-85, 2013. The problem Oligodendrocytes (OLs) produce the myelin sheaths ...

Central pontine myelinolysis is a neurological disorder. It results from damage to the myelin sheath of your brain cells in certain regions — usually the central pontine region — of your brain. The ...

Multiple sclerosis is a serious neurological condition that has no known cure. Although the causes are far from being known, we do know that the immune system erroneously attacks the protective ...
