Neurofeedback is a method of providing feedback to the brain about the quality of its own self-regulation. Through this feedback, the brain can be trained to regulate itself better. In this way, functions can be improved and dysfunctions can be reduced. The procedure can be used to treat a variety of disorders. However, neurofeedback is not a "cure-all." It does not automatically replace other forms of therapy such as drug therapy or psychotherapy. Therefore, it makes sense to discuss the use of neurofeedback in detail with your doctor. In many cases, the combination of different forms of therapy including neurofeedback should be considered.

The brain does what it wants - without asking us...

The human brain is a very complex structure. Information intake, processing and reaction, thought processes, moods and much more are controlled by a multitude of unconscious processes. The largest part of what happens in the brain every second is beyond our conscious control: We cannot perceive these complex processes consciously and can influence them even less. Even the brain itself does not receive any direct feedback about the quality of its activity. We perceive whether we are successful or not, whether we feel good or bad, whether we can concentrate or whether we fall asleep well and wake up refreshed. But although these things are a direct consequence of brain activity, the brain cannot tell which of its activities has contributed to well-being or unwellness, because the processes taking place in the brain change too quickly for the brain to recognize an immediate connection with the slower-occurring consequences.

... so we tell the brain if what it is doing is good.

Neurofeedback closes this gap. With neurofeedback, we can hold up a mirror to the brain, so to speak. The basis for this is electroencephalography (EEG), i.e. the measurement of electrical brain activity. Electrodes attached to the outside of the head with a paste are used to measure activity in various regions. The measurement results are processed by a computer and examined to determine whether or not the brain is showing adequate self-regulation at the moment. The test person receives feedback on the result via a screen, for example by displaying the image or film shown small and indistinctly or clearly recognizable and large, the sound to the film quieter or louder, the vibration of a tactile feedback giver stronger or weaker, an object in an animation faster or slower. This feedback changes continuously depending on the measurement results. In this way, the brain receives feedback that is directly related in time to its activity. The brain can thus change its behavior and adopt and maintain an appropriate state. The brain thus learns to change its self-regulation.
