It will go from the hillock (area where the axon starts) to the terminus (end of the axon near the synapse) in a wave like manner. He was saying that the reason for this is because the membrane is hyper polarized for a while after the action potential has past (more negative then the resting potential).

WebTwo processes which contribute to repolarization at the peak of the action potential are then engaged. First, the Na + conductance starts to decline due to inactivation. As the Na + conductance decreases, another feedback cycle is initiated, but this one is a … WebNov 25, 2016 · It is simply the change in permeability of the membrane to these ions that change the potential.
