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 ________.

Answer 1

Answer:

undergo no changes in strength, speed, or duration

Explanation:

A specific electrical signal being transmitted to a neuron is sufficient to generate an action potential. This happens because of the spread of a nervous impulse.

The stimulation of a neuron follows the law of all or nothing. This means that either the stimulus is sufficiently intense to excite the neuron, triggering the action potential, or nothing happens. There is no stronger or weaker action potential; it is equal regardless of the intensity of the stimulus. The smallest stimulus capable of generating action potential is called the threshold stimulus. In this case, if the magnitude of the received electrical signal doubles, the action potential will not change in strength, speed or duration.
