Determine whether each statement is true or false. i) The strength of an action potential is represented by the amplitude of the wave. A stronger stimulus will generate an action potential with a higher peak than a weaker stimulus.

Understand the Problem

The question requires a determination of the truth value of a statement regarding action potentials in neuroscience. It discusses whether the amplitude of the action potential wave correlates with the strength of the stimulus, specifically if a stronger stimulus produces a higher peak.

Answer

False.

The statement is false. The strength of an action potential is not represented by the amplitude; it is represented by the frequency of action potentials.

Answer for screen readers

The statement is false. The strength of an action potential is not represented by the amplitude; it is represented by the frequency of action potentials.

More Information

An action potential is an all-or-none response, and thus its amplitude remains constant regardless of stimulus strength. Instead, a stronger stimulus is encoded by a higher frequency of action potentials.

Tips

A common mistake is confusing the amplitude of individual action potentials with signal strength. The neuron code signal strength using frequency, not amplitude.
