The BrainHQ exercises are based on the scientific principle of brain plasticity—that the brain continually changes itself in response to stimuli, for better or for worse. In Livewired, neuroscientist and best-selling author David Eagleman explores and celebrates the brain’s natural plasticity, in a work that celebrated author Khaled Hosseini describes as “chockfull or mind bending ideas and dazzling insights.” How can a blind person learn to see with echolocation? How can a person learn to control a robot with their mind? These are just a tiny sampling of the fascinating questions Dr. Eagleman digs into in his latest book.
