According to the all-or-nothing principle, Select one: a. the amount of time a neuron must "rest" in between firing episodes is stable. b. if all the neurons in a network are not integrated, the "message" carried by the neurons will be lost. c. as a person ages, his or her neurological system slows down and the intensity of neural impulses decreases significantly. d. once the electrical impulse reaches a certain level of intensity, it fires and moves all the way down the axon without losing any intensity.

The correct option is d) 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.

Explanation:

In the field of biology, the all-or-nothing law can be described as a principle which focuses on the strength with which a nerve or muscle fibre responds to a particular stimulus, this strength being independent of the strength of the stimulus. The functioning of the impulse is just like the trigger of a gun. The more the force of a stimulus, the more will be the intensity of the nerve impulse.
