The magnitude of AP is the same for all stimuli that reach threshold regardless of the strength of the stimulus. But some stimuli that reach threshold are weaker than others. The deference lies in the frequency of APs generated by the stimuli. Strong stimuli generate a higher frequency of APs than do weaker stimuli

Work Step by Step
