In the nervous system a stronger stimulus is encoded by an i

In the nervous system, a stronger stimulus is encoded by an increased magnitude (height) of an action potential.

True

or

False

Solution

The statement is false.

Explanation: According to tha all-or-none law, the magnitude/height of an action potential or response given by a nerve to a stimulus depends upon the ability of the stimulus to cross the minimum threshold of the potential/magnitude. If a stimulus is sufficient enough to cross the threshold of the action potential, a full response will be generated by the nerve. However, if the stimulus fails to cross this threshold, no response will be generated at all. This holds true for both, nervous system and muscular system. Importantly, the longevity of a response depends upon the extent/time for which the stimulus was applied but the extent of response is independent of the strength of the stimulus.
