The nervous system is comprised of two primary cell types: neurons and glial cells ... glial cells form a membraneous sheath surrounding axons called myelin, thereby insulating the axon.

There are three main types of neurone: sensory, motor and relay. They have some features in common: A long fibre (axon) which is insulated by a fatty (myelin) sheath. They are long so they can ...

A new study has identified the protein hnRNP A1 as a key player in the production and maintenance of myelin, the fatty sheath ...

Nerve cells, or neurons, are the basic functional units of the nervous ... As the voltage increases along the axon, additional sodium channels open, propagating the signal. The myelin sheath made of ...

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 ...

The molecular mechanisms underlying myelin sheath destruction in multiple sclerosis ... Human CNS tissues were obtained from three subjects with MS, by biopsy or autopsy (8 weeks, 11 years and ...

The APOE4 variant causes cholesterol buildup in the cells that make protective fatty sheaths for neurons, possibly helping explain its ... while genes associated with myelin production were ...

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.

‘Scientists have discovered the crucial role of the hnRNP A1 molecule in maintaining #myelin sheath integrity. Could this be a new avenue for understanding #schizophrenia? #Neuroscience # ...

The researchers who scanned the brains of marathon runners suggested that some neurons in the brain may consume their own myelin, a fatty sheath that forms around nerve fibers in the brain.

Research published in the Journal of Neurochemistry has detailed the role of a protein, hnRNP A1, in the formation and stability of myelin ...
