Answer:
A threshold level depolarization.
Explanation:
In a neuron, the action potential threshold is known as the point of depolarization where the neuron fires, when the neuron reaches a point, it will fire and if it does not reach the point of depolarization, it will not fire and it helps to transmit the information to another neuron.
A neuron transmits the information with the help of electric impulses which are sent through its axon. When a neuron in an inactive phase, more +ve charged ions recline outside the axon membrane. In the process of stimulation, the axon membrane admits more Na+ ions and providing the neuron more +ve charge.
