"It's impossible to spend some time in the world of neurofeedback enthusiasts and not feel intrigued by the concept of a personal neuro-trainer, a device that helps you achieve the perfect mental state for the task at hand. That might sound ludicrous, but in a sense every coach or teacher you've ever had, from Little League to college English, was trying to train your brain to behave in new ways...The difference is that, unlike the neuro-trainer, the Little League coach can't see the changes in brain activity directly. Neurofeedback gives you a glimpse of that inner world." Johnson goes on to imply that the public awareness of neurofeedback and brain states for achieving peak performance will become more popular very rapidly.
