In а neurоphysiоlоgy lаb, а collection of axons (a nerve fiber) is placed in a chamber and an electrical stimulator is used to drive their membranes to threshold. Recording electrodes record the arrival of the action potentials at the end of the axons. As the frequency of the firing of the electrical stimulator increased, the frequency of the action potentials generated also increased, to a point. After that point, the frequency of action potentials generated remained constant, despite a continued increase in stimulator frequency. (10 points) - Explain the specific mechanism causing the "plateau" in action potential frequency. (5 points) - Explain why the recordings of the action potentials yielded different velocities of action potentials along the nerve fiber. Additionally, the recording of the arrival of action potentials
