A pioneering neuroscientist offers a new way of understanding how emotions drive behavior The Nature of the Beast , pioneering neuroscientist David J. Anderson describes a new approach to solving this problem. He and his colleagues have figured out how to study the brain activity of animals as they navigate real-life scenarios, like fleeing a predator or competing for a mate. His research has revolutionized what we know about animal fear and aggression.
