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 neuronal ...

Nura Bio raised $73.8 million to advance two experimental SARM1 inhibitors. The therapies are designed to block SARM1, a ...

Axons that are regularly stimulated do not pass on increases in performance to their neighbors, study on mice reveals. A complex network of nerve fibers and synapses in the brain is responsible for ...

Brain function depends on the swift movement of electrical signals along axons, the long extensions of nerve cells that connect billions of brain cells. The nerve fibers are insulated by a fatty layer ...

Researchers from the Icahn School of Medicine at Mount Sinai have discovered a molecular switch in neurons that limits the regrowth of damaged axonal fibers. The ...

Cross-section of nerve fibers from the mouse optic nerve: The dark dense lines show the insulating layer, the myelin. Highlighted in red is a swollen, clogged area of an impaired nerve fiber – caused ...

To rapidly transmit electrical signals in the brain, the long nerve fibers are insulated by specialized cells called oligodendrocytes. These cells also respond to the electrical signals of active ...
