11) Compare the propagation speeds of an action potential along an axon that is 10 µM in diameter and one that is 20 uM in diameter. You must have a quantitative answer. 12) How would the velocity of action potential propagation change if you quadrupled the membrane conductance? You must have a quantitative answer. 13) You discover a mutation in mice that causes them to suddenly lose their myelin sheaths. How would this mutation change the speed of action potential propagation and why?
