You can see just how intensively the brain works on a given problem, throwing away all unnecessary information. The brain contains mirror neurons, a type of brain cell that responds when we see another human do something. These neurons fire as if we were performing the action ourselves even though we are merely witnessing it. It is one of the ways we learn a skill. If] watch Tiger Woods's golf swing, my mirror neurons will fire as if I were practicing his swing. Later when I practice the swing for real, my neurons will have already been partially programmed. This effect is presumably the reason we enjoy watching sports; our mirror neurons allow us to begin acquiring a skill while sitting in an armchair! This is clearly a useful evolutionary trait but you do also need to practice for real! Mirror neurons also fire in response to witnessing emotions. When we see an actor laugh or cry, we experience their emotion as if for real. This helps us empathize with the person we are watching and is part of the reason we enjoy movies and plays. a ae — eee ee eee PIII ssS33 T Output Neural Network HOUSE_OVERSIGHT_015806
