Incognito: The Secret Lives of the Brain

Incognito: The Secret Lives of the Brain is a 2011 New York Times best-selling nonfiction book by American neuroscientist David Eagleman, an adjunct professor at Stanford University. The book explores the juxtaposition of the conscious 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 Incognito, Eagleman contends that most of the operations of the brain are inaccessible to awareness, such that the conscious mind "is like a stowaway on a transatlantic steam ship, taking credit for the journey without acknowledging the massive engineering underfoot."
