Action potential 4
By the action of the sodium-potassium pump, repolarisation continues until the transmembrane potential is returned to normal levels, i.e. the rest potential. The potassium channels will close when the
The loss of positive ions from the interior of a neuron produces
Extra info: The escape of potassium ions from the depolarised neuron cause repolarisation and returns the neuron to its resting potential.
