How can a blind person learn to see with her tongue or a deaf person learn to hear with his skin? What does a baby born without a nose tell us about our sensory machinery? Might we someday control a robot with our thoughts? And what does any of this have to do with why we dream? The answers to these questions are not right in front of our eyes; they're right behind our eyes. This book is not simply about what the brain is, but what it does. Covering decades of research to the present day, Livewired also presents new findings from Eagleman's own research, including new discoveries in synaesthesia, dreaming and wearable neurotech devices that revolutionise how we think about the senses.
