What does drug withdrawal have in common with a broken heart? How can a blind person learn to see with her tongue? Why do we dream at night, and what does that have to do with the rotation of the earth? The answers to these questions are right behind our eyes, in the three-pound organ carried in the vault of the skull. A masterful communicator, David Eagleman explores concepts ranging from synesthesia to wearable neurotech devices that revolutionize how we think about the senses.

"Intellectually exhilarating…. Eagleman's skill as teacher, bold vision, and command of current research will make this superb work a curious reader's delight."—Publishers Weekly (starred review)
