Incognito: The Secret Lives of the Brain is a New York Times bestselling non-fiction book by American neuroscientist David Eagleman, an adjunct professor at Stanford University. The book explores the juxtaposition of the conscious mind and the unconscious mind, with Eagleman summing up the text's themes with the question: "If the conscious mind - the part you consider to be you - is just the tip of the iceberg, what is the rest doing?" In July 2011, Eagleman discussed Incognito with Stephen Colbert on the Colbert Report.
