(A) EPP recorded from patient intercostal muscle depolarizes the resting potential from -73 to -43 mV but fails to elicit an action potential. (B) The EPP elicited by 10-Hz nerve stimulation over 5 min first facilitates and then decreases by -13% from baseline. Individual symbols represent means of 100 EPPs recorded over 10-sec intervals.
