Consider the different phases to this amazing event: 1. Depolarization (sodium channels open - Na+ rushes in - neuron become more positive - generates an action potential - +30 mV) 2. Repolarization (sodium channels close; potassium channels open - K+ rushes out; neuron rebalances voltage) 3. Hyperpolarization/Refractory period (neuron recharges; -90 mV) 5. Resting potential/state (neuron returns to -70 mV) [A0ucST0jyqw] |
