Neurofeedback is a form of biofeedback. What is Biofeedback? It is a simple concept, one with which we are very familiar from everyday life. The idea is: If you can sense it, you can change it. Biofeedback uses machinery to extend sensory perception into areas where we would normally be unaware. Normal activities of life depend on sensory feedback, e.g. balance, walking, holding objects.
Biofeedback gives the trainee ongoing immediate information about some body function. Knowing the information allows the trainee to modify the body function. Traditional biofeedback works with such things as muscle tension, finger temperature, skin conductance, heart rate, breathing rate, heart and breathing synchronisation, blood pressure.
Neurofeedback or EEG Biofeedback is a specific form of biofeedback which gives the trainee moment-to-moment information about the rhythmic electrical activity from various places in the brain (EEG or brain waves), and challenges the brain to modify certain components of it.
Similar to training other biological measures, the trainee is soon able to induce changes in the brain wave patterns. These changes lead to improved flexibility and stability of the brain waves in general, which leads to improved flexibility and stability of behaviour in response to external demands on the person in the course of day-to-day activity.
