All-Or-Nothing Principle

The principle that once the electrical impulse reaches a certain level of intensity (its threshold), it fires and moves all the way down the axon without losing any intensity.

Electrical Impulse

A sudden surge of energy in one direction, particularly in the context of neurons firing and transmitting information in the body.

Axon

A long, slender projection of a neuron that typically conducts electrical impulses away from the neuron's cell body.

Firing

In the context of neural activity, it refers to the action of a neuron when it sends an electrical signal down its axon to communicate with other neurons.
