Which of the following statements about action potentials is incorrect? Action potentials are unidirectional; they do not travel backwards During the absolute refractory period, another action potential cannot be generated An action potential that has an excitatory effect on the postsynaptic cell is called EPSP During the rising phase of an action potential, the membrane potential becomes more negative than it is at rest (-70 mV) At the peak of an action potential, the membrane potential is positive
