In an experiment, if both ends of a nerve fiber are stimulated simultaneously, the two action potentials will

Apass through the midpoint and conduct to the other end separately
Bmeet at the midpoint and then return to the starting point
Cmeet at the midpoint and stop conducting
Donly the stronger action potential will pass through the midpoint and reach the other end

Correct answer: C. meet at the midpoint and stop conducting

Action potentials in a nerve fiber are all-or-none events. They do not sum up or interfere with each other, so they will not meet and stop conducting at the midpoint.
