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

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

How does our nervous system operate so quickly and efficiently? The answer lies in a membranous structure called myelin. Aa Aa Aa All our activities — eating, walking, talking — are controlled by our ...

New research reveals that even a small loss of myelin—the protective coating around neurons—can severely disrupt how the brain sends and interprets sensory information.

Marathon runners experience reversible changes in their brain myelin. These findings indicate that myelin (a substance that surrounds the neurons) exhibits behavior that was previously unknown, and ...
