The fastest nerve fibers in the human body relay signals at speeds approaching 250 miles per hour, a rate that still leaves measurable delays when a baseball player tries to swing at a 95-mph fastball ...

A large pre-registered study shows that the effort-independent amplitude of the phrenic nerve compound muscle action ...

Two inherited neurological disorders that doctors have long considered diseases of the large, heavily insulated nerve fibers ...

This video illustrates the lifespan trajectory of the alpha process and its relationship with cortical myelination (T1w/T2w). Both the predicted myelination measure (derived from conduction efficiency ...

Doctors may use a range of tests to diagnose myasthenia gravis (MG), including blood tests, nerve conduction tests, and imaging tests. Myasthenia gravis (mai-uhs-THEE-nee-uh GRAH-viss) is a chronic ...

The disruption of axons—the thread-like part of nerve cells that transmits electrical signals—is associated with Alzheimer's disease. One way axonal function may be hindered is through damage to the ...

Chronic inflammatory demyelinating polyneuropathy (CIDP) affects the peripheral nerves. Tests to diagnose this condition include nerve conduction studies, electromyography, and sometimes an MRI. CIDP ...

As we age, our body’s nervous system starts to slow down. The nerves that tell our muscles to move don’t fire as quickly. That decline can shape how we move, react, and perform. Resistance training ...
