You cringe when a coworker gets a paper cut and cheer when a movie hero gets the girl. That’s because for an instant, it’s just as if these events are happening to you—and, in a way, they are.
Years ago, scientists studying specific nerve cells in macaque monkeys’ prefrontal cortexes found that the cells fired when the monkeys threw a ball or ate a banana.
But here’s the surprise: these same cells fired when the monkeys watched another monkey performing these acts. In other words, when Monkey #1 watched Monkey #2 toss a ball, the brain of the first monkey reacted just as if it had tossed the ball itself.
