You and your lab partner have prepared a frog nerve for gathering data on action potentials. You connect an electronic stimulator to the nerve and ask your partner to gradually increase the voltage until you see an action potential. Your partner says that the voltage knob is stuck, that is, it will not increase the voltage. Is there another way to trigger action potentials using this stimulator? If so, what do you tell your partner to do?

Your lab partner can increase the stimulus frequency instead. A higher frequency of stimuli can result in temporal summation of graded potentials such that the lower voltages sum to threshold.
