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 ...

Neuron 59, 581–595 (2008). Franklin, R. J. & ffrench-Constant, ... The myelin sheaths generated during remyelination are typically thinner and shorter than those generated during developmental ...

Multiple sclerosis, a neuroinflammatory disease that affects nearly 3 million people worldwide, causes a loss of myelin, the fatty sheath that covers nerve cells in the brain and spinal cord.

The myelin sheath coating a neuron helps speed up the transmission of electrical signals in the brain. Now researchers have captured footage of a neuron receiving its coating.

Neuron Function Synapses Neural synapses are junctions between neurons that permit neural communication. ... As the voltage increases along the axon, additional sodium channels open, propagating the ...

In the Sept. 1 Neuron, scientists demonstrate that the protein neuregulin-1 type III (NRG1-III), which is produced by nerve cells, is essential to triggering glial cells to make myelin.

Multiple Sclerosis Insights from Views of Myelin Formation at Neuron-Glial Synapses January 12, ... “There may be a way to intervene so that you can increase the myelin sheath,” he said.

Myelin is the “insulation” that wraps around nerve axons in the brain. Last month, Dr. George Bartzokis, director of the UCLA Memory Disorders and Alzheimer’s Disease Clinic, ...
