Animation: Action potential

Watch or download our animation about the action potential

Note: When we reviewed this animation, we noticed that we’d made a mistake. Maybe you spotted it too. 

When the sodium channels open and sodium ions move into the cell, this causes the resting potential to increase, not decrease as it says in the animation. Sorry about that!
