Sometimes our brains are operating too fast, like in flight or flight mode, when we are not at risk, resulting in the brain overworking. Sometimes the brain is operating too slowly when we need it focused for learning and relating. The sensory feedback and the brain's response is the brain training itself to a regulated, optimal state, thus significantly reducing or eliminating the resulting symptoms of a disregulated state. Nothing is going into the brain. It is simply the brain receiving feedback and it will change itself. Results are long-lasting or even permanent. We compare it to riding a bike. Once your brain learns to balance on two wheels, you can go for years without riding a bike, but your brain instantly remembers how to do it. Neurofeedback works the same way!
