WebAnimation 6.8. A voltage change that reaches threshold will cause voltage-gated sodium channels to open in the axonal membrane. The influx of sodium causes the rising phase of the action potential, but the ion flow also depolarizes nearby axon regions. As the depolarization reaches threshold, the action potential moves down the axon. Web2. Local potential - depolarization occurs in the membrane, but the channels are still closed (until it reaches the threshold) 3. Action potential - once it reaches the threshold, sodium channels open and allows sodium ions to rush into the membrane. Now the membrane overshoots to positive 4.
