(Medical Xpress)—We've done a number of articles recently about some amazing individuals developing personalized treatments to their own currently uncurable disease. Whether it is a rare orphan disease like Sanfilippo Syndrome ...
Students of physiology are invariably taught that the primary function of myelin is to insulate nerves. In particular, to make action potentials more efficient by increasing the thickness of the membrane and thereby decreasing ...
Nerve cells stripped of their insulation can no longer carry vital information, leading to the numbness, weakness and vision problems often associated with multiple sclerosis. A new study shows an overlooked source may be ...

(Medical Xpress)—Myelin is an electrically insulating layer, or sheath, made of protein and fatty molecules, and synthesized by cholesterol-rich oligodendrocytes, that forms around neurons and allows electrical impulses ...
The ability to construct complex myelin sheaths around axons is one of the greatest vertebrate inventions since the hinged jaw.
Scientists have identified 29 new genetic variants linked to multiple sclerosis, providing key insights into the biology of a very debilitating neurological disease. Many of the genes implicated in the study are relevant ...

Scientists have found that 93% of the lipids in brain tissue are distributed differently in the white and gray matter, the subcortex, the visual and motor cortices, and the prefrontal cortex, which is responsible for decision-making, ...
