Neurofeedback is direct training of the brain function, whereby the brain learns to function more efficiently. We observe the brain in action from moment to moment. We show that information back to the person. And we reward the brain for changing its own activity into more appropriate patterns.
This is a gradual learning process. It applies to any aspect of brain function that we can measure.
Neurofeedback is also called EEG Biofeedback, because it is based on electrical brain activity, the electroencephalogram, or EEG. The signals picked up by the electrodes are sent to a computer, where they are processed. Key brainwave frequencies are turned into a combination of images and sound feedback, which the person watches and hears. This is done in “real-time,” so the person sees exactly what is going on in their brain as they think certain thoughts, feel stressed, or feel relaxed.
