(Medical Xpress)—It is widely know that the grey matter of the brain is grey because it is dense with cell bodies and capillaries. The white matter is almost entirely composed of lipid-based myelin, but there is also a ...
(Medical Xpress)—A major question regarding how axons acquire a coat of myelin, is the role of spiking activity. It is known that in culture systems oligodendroctyes will at least try to wrap anything that feels like an ...
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 ...

For oligodendrocytes—the central nervous system cells critical for brain function—age may not bring wisdom, but it does come with the power to cling to life for much, much longer than scientists knew. That's according ...

Regulatory T lymphocytes are cells that are responsible for regulating the immune system and have regenerative functions in many contexts, including myelin restoration. To determine if the function of these cells is impaired ...

A complex network of nerve fibers and synapses in the brain is responsible for transmission of information. When a nerve cell is stimulated, it generates signals in the form of electrochemical impulses, which propagate along ...

Multiple sclerosis (MS) is a neurological disease that usually leads to permanent disabilities. It affects about 2.9 million people worldwide, and about 15,000 in Switzerland alone. One key feature of the disease is that ...

Myelin is an insulating sheath around axons—the processes connecting nerve cells—that is mostly composed of lipids and proteins. It enables rapid conduction of electrical signals and supports neuronal integrity and function. ...
