More TED Talks What happens in your brain when you hear a good story? In the lab of neuroscientist Uri Hasson, experiments reveal that even across different languages, our brains show similar activity, or become "aligned," when we hear the same idea or story.

Join him as he details two compelling works and shares the motivation behind his art. "Only through more thoughtful dialogue about history and race can we evolve as individuals and society," he says.
