New research reveals that Alzheimer's disease may impair nerve function not by reducing myelin, but by altering the proteins ...

Previous work identified OPCs—dividing cells in the adult brain that play a crucial role in the brain's maintenance—as one of the brain cell types that give rise to these tumors.

Myelin is a fatty substance that surrounds and insulates nerve fibers in the brain and spinal cord, forming a sheath that facilitates the rapid transmission of electrical signals between neurons.

He suspects the brain routinely taps into myelin for fuel, just at levels too low to detect—except during extreme events like a marathon. But there’s no need to panic, he says.

People exposed to higher levels of air pollution may be more likely to develop meningioma, a typically noncancerous brain ...

Running an entire marathon takes a lot of energy. Neuroscientist Carlos Matute knows this: he's run 18 of them. He wondered how runners' bodies get the energy they need to make it to the finish line.

It houses the nerves that send messages back and forth between your brain and body. Tumors can grow along the spinal cord, ... These cells form the myelin sheath that protects your nerve cells.
