Nerve fibers in the brain and spinal cord are wrapped in an insulating sheath known as myelin. For a long time, this barrier, ...

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 ...

Multiple sclerosis (MS) is a serious neurological disease that usually causes permanent disability. Approximately 2.9 million people are affected worldwide, 240,000 in Germany alone. The exact cause ...

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 ...

Myelin loss disrupts the coordination of signals between brain regions, impairing the accurate processing of information, researchers found.

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 ...

Researchers at the Netherlands Institute for Neuroscience have discovered that the energy management of inhibitory brain cells is different compared to excitatory cells in our brain. Why is that 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 ...
