{"Image DocumentName": "The Refractory Period Figure 12.15", "Image ImageDescription": "during an action potential and for a few milliseconds after, it is difficult or impossible to stimulate that region of a neuron to fire again. refractory period \u2013 the period of resistance to stimulation. two phases of the refractory period. absolute refractory period. no stimulus of any strength will trigger AP. as long as Na+ gates are open. from action potential to RMP. relative refractory period. only especially strong stimulus will trigger new AP. K+ gates are still open and any affect of incoming Na+ is opposed by the outgoing K+ refractory period is occurring only at a small patch of the neuron\u2019s membrane at one time. other parts of the neuron can be stimulated while the small part is in refractory period.
