My professor said that increasing the amplitude (the amount of depolarization e.g. depolarizing from -80 mV instead of -50 mV) leads to a greater conduction velocity.

  • $\begingroup$ Do you mean that larger-amplitude action potentials have larger speeds? In that case your example is incorrect, as an action potential generated from a resting potential of -80 mV has a larger amplitude than an action potential generated from a resting membrane potential of -50 mV. $\endgroup$ – AliceD Sep 17 '15 at 13:09

    $\begingroup$ @AliceD yes that's what I mean, -80mV has a larger amplitude and will have a greater conduction velocity through the neuron as compared to a 50mV resting potential. Why is this? $\endgroup$ – user1084113 Sep 19 '15 at 9:42
