Final answer:
Mirror neurons are involved in both observational learning and visualization, where mental rehearsal can enhance neural connections and performance.
Step-by-step explanation:
The question pertains to mirror neurons, which are specialized brain cells that appear to enable mimicry and observational learning. Considering the statements provided, the correct answer is E. When you visualize doing something the correct way, you can strengthen connections and improve performance. This highlights the role that mirror neurons can play in not only observing and imitating action but also in mental rehearsal and visualization. Mirror neurons are not limited to activation during the direct visualization of an action or while looking at one's own reflection, and they can indeed be activated by visualizing actions mentally.
