Neuronal Impulse and Action Potential

This site includes text and illustrations to show the recording of electrical charge inside and outside a neuron during its resting state and during an action potential. An electrical current travels along the cell membrane of a neuron when it is stimulated. The rapid movement or transmission of an action potential along the cell membrane is called the neuronal impulse. The neuronal impulse is an all-or-nothing event that occurs only when stimulation is strong enough.
