WebWhat characterizes repolarization, the second phase of the action potential? Once the membrane depolarizes to a peak value of +30 mV, it repolarizes to its negative resting value of -70 mV. What event triggers the generation of an action potential? WebThere are three main events that take place during an action potential: A triggering event occurs that depolarizes the cell body. This signal comes from other cells connecting to the neuron, and it causes positively charged ions to flow into the cell body.
