a type of brain cells that are activated both when an individual performs an action and when they observe another individual performing the same action.
you see someone smile, your mirror neurons activate, allowing you to experience the feeling of happiness or joy that the other person is experiencing. Similarly, when you watch a skilled athlete perform a complex movement, your mirror neurons activate, enabling you to understand how the movement is performed and potentially allowing you to learn the movement yourself through imitation.
