In long-lived animals, renewed but thin myelin sheaths are enough to restore the impaired nervous system and can do so for years after the onset of disease, scientists have discovered. In the central ...

To rapidly transmit electrical signals in the brain, the long nerve fibers are insulated by specialized cells called oligodendrocytes. These cells also respond to the electrical signals of active ...

Eye-exam_G_819479332 Thinning of the retinal nerve fiber layer has been linked to worsening cognitive function and may be valuable in identifying individuals who may be at risk for cognitive decline.

"The human body is the most complex system ever created." Bill Gates is right on. One example of the complexity is the ...

Arteries can narrow with fatty buildup. Blood struggles to move. Oxygen drops. A heart attack can follow, and it remains the world’s top killer. Researchers at the University of California San Diego ...

Analyzing molecular changes in two types of peripheral nerves that are affected in diabetic peripheral neuropathy – the sural, which carry sensory signals, and the tibial, which carry both sensory and ...

Neurons are the basic functional units of the brain. They have three main parts: dendrites, a cell body, and an axon (more commonly known as a nerve fiber). Dendrites look like twigs growing off the ...

Silent cells deep in your spinal cord may hold a surprising key to healing after devastating injuries and brain disease. A ...

Small Fiber Neuropathy (SFN) is a disorder in which the small diameter sensory myelinated (Aδ) and unmyelinated (C fiber) nerves of the peripheral nervous system are damaged. The peripheral nervous ...
