Axons that are regularly stimulated do not pass on increases in performance to their neighbors, study on mice reveals. A complex network of nerve fibers and synapses in the brain is responsible for ...

Nervous system development requires billions of neurons to migrate to the appropriate locations in the brain and grow nerve fibers (axons) that connect to other nerve cells in an intricate network.

Scientists have used gene therapy to regenerate damaged nerve fibers in the eye, in a discovery that could aid the development of new treatments for glaucoma, one of the leading causes of blindness ...

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 ...

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 ...

Past neuroscience studies have identified a TAR DNA-binding protein that plays a key role in ALS, known as TDP-43. This protein, which generally regulates RNA processing (i.e., how genetic information ...

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 ...

Researchers from the Icahn School of Medicine at Mount Sinai have discovered a molecular switch in neurons that limits the regrowth of damaged axonal fibers. The ...
