How does myelination happen

In contrast, among the myelinated nerve fibers, axons are mostly covered by myelin sheaths, and transmembrane currents can only occur at the nodes of Ranvier where the axonal membrane is exposed.

These are known as nodes of Ranvier. The presence of myelin as an internodal insulator ensures that membrane depolarization can only occur at the nodes. The result is rapid, saltatory (from the ...

It is now increasingly appreciated that not only can myelination occur throughout much of adult life, but also that myelination is responsive to neuronal activity. This raises the possibility that ...

We can see a future where no one has to worry about MS getting worse but, for that to happen, we need to find ways to repair damaged myelin. This research sheds light on why cells that drive myelin ...

Our body giveswarning signs that there's a problem and our hands especially can fire off signals indicating there's a major health issue.

Multiple sclerosis is a potentially debilitating inflammatory disease in which the body’s immune system eats away at the protective myelin sheath that covers the nerves. Thus, the condition is called ...

One perspective is the identification of previously under-recognized treatment targets for existing antipsychotic drugs, including myelination and mediators of inflammation. A second perspective is ...

Schwann cells, for example, help nerve cells to transmit information faster by wrapping their long extensions in a fatty membrane called myelin. When myelin is not produced properly, this can disturb ...

It is thought that endogenous remyelination in the CNS occurs through the action of oligodendrocyte precursor cells generating new oligodendrocytes, which encourage the production of myelin in ...

Myelin oligodendrocyte glycoprotein (MOG) antibody-associated disease (MOGAD) is the most recently defined inflammatory demyelinating disease of the central nervous system (CNS). Over the last decade, ...

Misdiagnosis might occur in some cases with serious therapeutic repercussions. However, introduction of several new biomarkers such as aquaporin-4 IgG and myelin oligodendrocyte glycoprotein IgG has ...
