The Action Potential

Edit 5th September 2011:

Note there is a small error at around 2:20. The movement of ions to correct hyperpolarisation occurs by active transport using the sodium-potassium pumps (purple block) rather than by diffusion as the narration states. Thanks to user SirBlibofDoh for pointing this out.


The action potential for A level biology.


Produced as part of a final year undergraduate project into the use of podcasting in education at the University of Sussex.
