For thousands of years, we've searched to answer the question: Who are we? Today, science has brought us closer than ever to the answer. This hour, TED speakers share ideas on what makes us ... us. In a brand new interview, neuroscientist Anil Seth explores how our brains construct our conscious reality--everything we perceive, from objects to emotions. Other guests from the original 2016 episode include biochemist Sam Sternberg, psychologist Steven Pinker, and humorist Ze Frank.
