If the conscious mind is just the tip of the iceberg, what is the rest doing? In this book, David Eagleman navigates the depths of the subconscious brain to illuminate its mysteries. Why can ones foot move halfway to the brake pedal before becoming consciously aware of danger ahead? How is the brain like a conflicted democracy engaged in civil war? What do Odysseus and the subprime mortgage meltdown have in common? And why is it so difficult to keep a secret? Taking in brain damage, plane spotting, dating, drugs, beauty, infidelity, synesthesia, criminal law, artificial intelligence, and visual illusions, 'Incognito' aims to be a subsurface exploration of the mind and all its contradictions.
