Have you ever imitated your favorite actor? Or talked like a person whom you like. Ever made fun of any person by mocking him?Of course, I too did. It's a lot fun in doing so. But why do we imitate?
Some scientists say that "Mirror Neuron System" are responsible for this phenomena. Mirror neurons get excited while we see others doing some actions and even when we do the same. Learning by imitation is done with the help of these neurons. Empathy towards others is also due to these neurons. We may experience the emotion when the other person experiences an emotion.
An interesting example which takes advantage of these Mirror Neurons is "Advertising". Suppose, our favorite actor drinks some beverage stylishly in an Ad, we will also follow him. Don't we?
And finally, if we make fun of our Profs by imitating their silly actions, its not our fault, blame it on these interesting Mirror Neurons.
