Which of these statements describes the result of a neuron being experimentally stimulated at both ends simultaneously
A)The action potentials pass in the middle and travel to the opposite ends.
B)The action potentials meet in the middle and are then propagated back to their starting positions.
C)The action potentials stop as they meet in the middle.
D)The stronger action potential overrides the weaker action potential.

Question

Quizplus · Accepted Answer

When a neuron is experimentally stimulated at both ends simultaneously, the action potentials will meet in the middle and then stop. This is because action potentials have refractory periods during which they cannot be regenerated, and the refractory periods of the two opposite-moving action potentials overlap in the middle, preventing any further propagation of electrical activity.
