Mirror neurons fire upon observation of an action and “mirror” the behavior of others (as though the observer were itself acting). Dr. Giacomo Rizzolatti discusses why we do not immediately imitate actions upon observing them. The main reason is that the parietal-frontal circuit is under control of the prefrontal lobe. Information is available and ready to be executed but is continuously stopped by our prefrontal lobe (our will stops imitation from taking place). He discusses ailments where there is a breakdown in this inhibition: Imitation and utilization behavior occur because the prefrontal lobe is no longer inhibiting action.
