Question

a particular electrical signal being transmitted to a neuron is sufficient to generate an action potential. if the magnitude of the incoming electrical signal is doubled, the action potential will ________. last twice as long be twice as strong undergo no changes in strength, speed, or duration travel twice as fast down the axon

Explanation:

The all - or - none law of action potentials states that once the threshold for an action potential is reached, further increases in the strength of the stimulus do not affect the strength, speed, or duration of the action potential. A sufficient electrical signal to generate an action potential means the neuron has reached its threshold. Doubling the magnitude of the incoming signal beyond the threshold will not change the characteristics of the action potential.

Answer:

undergo no changes in strength, speed, or duration
