There are two generations of neurofeedback. Out of the first we got protocol-based where you are using an initial brain map and comparing it to the client's brain and then using entrain and migrate techniques to create state change. And out of the second generation came Dynamical NeurOptimal neurofeedback, which is the system we use. Here the brain gets a brain map of itself shown to itself moment by moment through analysis of 20 targets up to 60 Hz. And with that information it reorganizes itself.
