electrical impulse
Nerve's traveling charge
An electrical impulse is a brief surge of electrical activity that travels along a pathway, especially a nerve fiber.
The term appears most often in biology, where nerve impulses carry signals through the body: The brain sends electrical impulses to the muscles.
The phrase also describes any sudden, short-lived electrical signal in a circuit or system.
