    Hi,

    Can someone please explain (preferably in layman's terms) why an action potential can only be propagated in one direction along an axon? I've tried looking in various text books and online but I just don't get the concept...

    Thanks!

    There is a rest period (refractory period) after the release of the action potential which means the signal can’t travel back towards its origin as that area isn’t ready to conduct again. So it must travel in one direction otherwise the signal would be cut off and not propagate at all.

    You already asked this in a different thread and 3 people answered it lol.. try and get your head around the concept of refractory period, it might even help to understand how an action potential propagates in the first place because if you don't understand that then you can't understand what the refractory period is. I'd be willing to explain it all if you give me the time
