WHAT MAKES YOU, YOU? The brain has long been a source of fascination. In 1819, the radical thinker and surgeon William Lawrence put it like this: "It is strongly suspected that a Newton or Shakespeare excels other mortals only... by having an extra inch of brain in the right place."Today, many such suspicions are certainties. We understand the structures of the brain, minor and major, and their roles in making us who we are. We can record electrical signals from individual brain cells or networks of them. Imaging teCNology lets us see both snapshots of the brain and also videos of it in action. We can follow connections within the brain and watch them reform after an injury.How Your Brain Works explores what's going on inside your head, and what makes you, you. It looks at teCNiques for controlling the brain using electric and magnetic fields, as well as investigating the latest teCNologies that allow you to control the outside world using your mind alone.ABOUT THE SERIESNew Scientist Instant Expert books are definitive and accessible entry points to the most important subjects in science; subjects that challenge, attract debate, invite controversy and engage the most enquiring minds.
