Neurons have a period called the absolute refractory period during which they cannot generate another action potential, regardless of the strength of the stimulus. This period coincides with the time of Na+ permeability changes and immediately after, ensuring that each action potential is a distinct, all-or-nothing event.

B) is absolutely refractory to stimulation during the time Na+ permeability is changing, and immediately following this change
C) can generate another action potential during the time Na+ permeability is changing and immediately following this change, but only if stimulus strength is increased
