The five senses shape all our experience, but we still don't fully understand them. This episode, TED speakers explore how our brains make sense of sensation, and how our minds manufacture "reality." Guests include astronomer Wanda Diaz Merced, geneticist Nicole Garneau, author Isaac Lidsky, zoologist Tristram Wyatt and neuroscientist David Linden. (Original broadcast date: January 20, 2017.)
