Which of the following does NOT correctly match a term with its description? Depolarization --- Period during which sodium ions diffuse out of the neuron due to a change in permeability for these ions. Repolarization --- The interior of the cell becomes more negative due to the opening of potassium ion gates. Relative refractory period --- An exceptionally strong stimulus can trigger a response (action potential). Absolute refractory period --- Period during which the neuron cannot respond...
