Demyelination is damage to the myelin sheath around nerves. ... In unmyelinated neurons, a signal can travel along the nerves at about 0.5 to 10 meters per second, ...

Panel A shows leukocortical demyelination; Panel B subpial demyelination (arrows delineate an area of cortex with preserved myelin); Panel C intracortical demyelination (arrows), with neurons in ...

Mitochondrial abnormalities, or problems in cells' powerhouses, contribute to nerve cell death linked to motor control in MS, ...

Through their pattern of firing, neurons influence the behavior of the cells that upon maturation will provide insulation of neuronal axons, according to a new study publishing 22 August in the ...

Demyelination is the process in which the myelin sheath ... "Inside the cerebellum are special cells called Purkinje neurons," Tiwari-Woodruff said. "These large, highly active cells help coordinate ...

Importantly, the loss of axons and their neurons is a major factor determining long-term disability in patients, although the primary cause of the disease is demyelination.

But myelin becomes damaged in demyelinating diseases like multiple sclerosis, leaving neurons without their sheaths. Researchers now believe they have found a way to help the brain replace damaged ...

UC Riverside study may lead to new treatments for multiple sclerosis. Multiple sclerosis (MS) affects an estimated 2.3 ...

The disabling effects of multiple sclerosis may be caused in part by damaged connections between neurons, and this can be seen in the eye, UC San Francisco researchers have found. They showed that ...

Neurons connected in a neuronal network. [Christoph Burgstedt/Getty Images] Demyelinating diseases are any conditions that damage the protective coating on nerve cells, the myelin sheath.
