Myelin, the fatty substance that sheaths and insulates the axons of neurons, is responsible for aiding the quick delivery of signals throughout the brain. Too little myelin leaves the cells vulnerable ...

This myelination, as it is called, can greatly increase the speed of signals transmitted between neurons (known as action potentials). Indeed, the evolution of myelin allowed vertebrates to ...

Recent MRI research suggests our brains can turn to an unexpected source of fuel in times of need, like running a 26.2-mile ...

and myelin sheaths surrounding the axon that accelerate action potential propagation. Neurons can also be categorized by their basic structure. Unipolar neurons have one nerve process that acts as ...

While most of the brain’s neurons are thought to be created before birth, an explosion in neural connections, the myelination of axons, and other developments boost its total volume. Research ...

(E) Myelinated nerve fiber reproduced in vitro by coculture of rat dorsal root ganglion neurons and Schwann cells. Myelin segments are stained in red by an antibody to myelin basic protein ...

Multiple sclerosis (MS) is a chronic condition affecting the central nervous system. In MS, the immune system attacks the protective myelin coating around nerve fibers, disrupting nerve ...

Running a marathon isn’t just a workout for your legs—it’s an all-out endurance test for your entire body. And yes, your ...

Researchers found marathon running causes a temporary reduction in brain myelin, especially in areas related to motor ...

Marathon running causes a temporary decline in brain myelin content, but levels return to normal within two months. This ...

Neurons are cells in the body that are responsible for transmitting electrical signals through the nervous system. Different types of neurons affect the ability to move, which begins as an impulse ...
