Which of the following would most likely occur if you experimentally depolarize the middle of an axon to threshold using an electronic probe?
A) no action potential will be initiated
B) an action potential will be initiated and proceed only in the normal direction toward the axon terminal
C) an action potential will be initiated and proceed only back toward the axon hillock
D) two action potentials will be initiated and will proceed in opposite directions
