  • @ramasyean - yes - by way of the sodium-potassium pump

  • so when the next signal comes, the potassium goes in and the sodium goes out?

  • @MrGamer348 Actually, the potassium and sodium balance inside & outside the cell is restored very shortly afterward - restoration is required before another impulse can travel down the axon.

  • Awesome. I knew youtube wouldn't fail me. 

  • Great! Really very good.

    It would be better if they represented the sodium and potassium gate opening and closing, but it's still a great video.
