C: During the ~0.5 ms period of the action potential in which sodium ions are rushing into a nerve cell, the nerve cannot respond to any stimulus not matter how strong the stimulus. Because of the impossibility of response, this period is called “absolutely” refractive. (refractory = resisting ordinary methods)
