If a neuron were experimentally stimulated at both ends simultaneously:
A) The action potentials would pass in the middle and travel to the opposite ends.
B) The action potentials would meet in the middle and then be propagated back to their starting positions.
C) The action potentials would stop as they met in the middle.
D) The strongest action potential would override the weaker action potential.
E) Summation would occur when the action potentials met in the middle, resulting in a larger action potential.

Question

When action potentials meet in the middle, they cancel each other out due to the refractory period, preventing further propagation.
