B) threshold potentials

E) neither graded potentials nor action potentials

Question

Quizplus · Accepted Answer

Action potentials are affected by refractory periods, which are times during which a neuron is unable to fire a new action potential or where it is more difficult to fire another action potential, due to the state of ion channel inactivation. Graded potentials do not have refractory periods in the same way action potentials do.
