Diffusion magnetic resonance imaging (dMRI) is commonly used to assess the tissue and cellular substructure of the human brain. In the white matter, myelinated axons are the principal neural elements ...

Analyzing the structure of neuronal fibers with single axon resolution in large volumes is a challenge in connectomics. Different technologies try to address this goal; however, they are limited ...

The evolutionary prerequisites of myelin -- the fatty substance that insulates axons and enables rapid communication between cells of the nervous system in jawed vertebrates. The evolutionary ...

Multiple sclerosis (MS) affects millions of people worldwide, and there is currently no cure for this disease of the central nervous system. Damage to the nerve fibers, also called axons, is ...

Multiple sclerosis (MS) is a serious neurological disease that usually causes permanent disability. Approximately 2.9 million people are affected worldwide, 240,000 in Germany alone. The exact cause ...

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 ...

Researchers shed new light on how myelin loss might underpin aberrant brain activity which have been observed in people with multiple sclerosis. The study suggests that myelination, however patchy on ...

Axons are the brain’s information highways, transporting cellular cargo, chemical signals, and electrical impulses to other cells. These “roads” are typically depicted as smooth and cylindrical, with ...

(a) Schematic illustration of the core-shell configuration of the myelinated axon with efficient neural action potential transmission capability. The hydrogen bonds and Van der Waals forces between ...

The ultrathin tendrils that zip messages around the nervous system are often drawn as smooth lines. But a new study adds some flourishes to that classical picture. Like a garland of cranberries hung ...

Multiple sclerosis (MS) is a serious neurological disease that usually causes permanent disability. Approximately 2.9 million people are affected worldwide, 240,000 in Germany alone. The exact cause ...
