Schwann Cells: Cells in the peripheral nervous system that support nerve regeneration and myelination (the process of forming a protective sheath around nerves). Macrophages: Immune cells that ...

During the pathogenesis of Parkinson’s disease (PD), α-synuclein pathology may originate in peripheral organs and spread to the CNS. Using human tissue samples and multiple approaches in mouse ...

Stop the Spread. Injecting saline into mouse kidneys did not affect the left or right substantia nigra (top). Injecting fibrils of α-synuclein ablated about half of the dopaminergic neurons (middle ...

and the peripheral nervous system (PNS). The CNS includes the brain and spinal cord, and the PNS is made up of all the body’s remaining nerves. The PNS can also be subdivided into smaller components: ...

Various diseases can be treated by stimulating the vagus nerve in the ear with electrical signals. However, this technique does not always work. A study has now shown: The electrical signals must be ...

Following an injury, the brain tries to repair the damaged nerve fibers . Unfortunately, the repair process often succeeds only partially, meaning many patients experience lasting damage to their ...

Myelin is an insulating layer of lipids and proteins surrounding nerves. Myelin damage can cause problems with the nerves’ ability to send and receive electrical messages. Inflammatory disorders ...

Of further relevance, TMS techniques reliably distinguish ALS from mimic disorders, despite a compatible peripheral disease burden, thereby suggesting a potential diagnostic utility of TMS in ALS.
