We have a brain for one reason and one reason only -- and that’s to produce adaptable and complex movements. Movement is the only way we have of affecting the world around us . . . I believe that to understand movement is to understand the whole brain. And therefore it’s important to remember when you are studying memory, cognition, sensory processing, they’re there for a reason, and that reason is action.
