What is the term for the event when a neuron's electrical charge briefly becomes less negative or positive, triggering a neural signal?

Explanation

An action potential occurs when the neuron's membrane potential rapidly shifts from a negative to a positive value, initiating the transmission of a nerve impulse. In contrast, resting potential refers to the stable, negative charge of a neuron at rest. Impulse facilitation and inhibition relate to modulation of signals, not the initial charge change.
