Axons are the longest cellular projections of neurons relaying electrical and biochemical signals in nerves and white-matter tracts of the nervous system. As such, they are critical for neuronal ...

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 ...

Myelin is an insulating sheath around axons - the processes connecting nerve cells - that is mostly composed of lipids and proteins. It enables rapid conduction of electrical signals and supports ...

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 ...

An axon is the part of a neuron that sends a signal to other cells. Axons extend from the cell body to contact other cells, generally forming synapses between the two cells. These axons can be very ...

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 team ...

Brain cell signals travel along axons, the thin wire-like extensions of neurons, moving signals along the membrane in a pearl ...

Adaptability may be the defining characteristic of our species — not our large brains, our long legs, or our ability to make tools, but our ability to rapidly learn new skills and behaviours in ...

Efficient removal of abnormal myelin allows survival of nerve fibers targeted by adaptive immune cells, according to a novel study. Myelin is an insulating sheath around axons -- the processes ...
