As brain sciences have recently advanced, their applications to clinical medicine, engineering, and even marketing and management are extensively performed and attempted. In this talk, I will introduce basic concepts and principles of brain dynamics, and the methodolgies for investigating brain functions and consequently the mind. I will show how this mind-reading technology can be applicable to many novel field and this interdisciplinary approach can achieve significant outcomes. And I also stress the critical role of physicsists in this neuroRevolution.
