Experiment ResultsPredict Question Stop & Think Questions The time after an action potential when a second action potential cannot be generated nomatter how intense the stimulus is called the1 The time after an action potential when a second action potential can be generated only ifthe stimulus intensity is increased is called the2 The term frequency refers to3 The purpose of this activity is to explore4 Predict Question: What effect will the increased stimulus intensity have on the frequency ofaction potentials?1 At the site of stimulation, the stimulus keeps the membrane of the axon at threshold for a long time, but this depolarization does not spread to the recording electrode. After one action potential has been generated and the axon has fully recovered from its absolute and relative refractory periods, the stimulus is still present to generate another action potential.
