Nerve fibers are surrounded by a myelin sheath. Scientists have now made the first-ever 'live' observations of how this protective layer is formed. Nerve fibers are surrounded by a myelin sheath.

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

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 ...

New research reveals that when gut bacteria closely resemble the myelin sheath that protects nerve fibers, the immune system can become confused and attack both — accelerating multiple sclerosis.

Researchers have found that Schwann cells, a special type of cells are capable of generating protective myelin sheath covers for the nerves at rates higher than earlier believed. Senior author Dr.

New work in mice is revealing how losing insulation on just a few nerve fibers can throw off the timing of brain signals and ...

In a new study, mice bearing a gene deletion associated with autism spectrum disorder (ASD) showed evidence of slower cognition. Another finding: cells that make myelin, a sheath around nerves that ...

Heat sensitivity in multiple sclerosis is well known, but doctors say cold weather can also worsen symptoms. From nerve ...

Research shows how cells respond to brain injury by releasing corticotropin-releasing hormone, which helps to repair damage.
