Neurofeedback is a computer-assisted training method for self-regulating unconscious processes in the brain. For a number of mental health conditions, such as depression or ADHD, the positive effects of neurofeedback have been demonstrated in science and practice for years. But neurofeedback is also increasingly used in competitive sports, music, and top management as a natural method for improving concentration and managing stress.Using a computer-assisted EEG (electroencephalogram), various brain activities are measured. These can be clearly associated with specific mood states (e.g., concentration, relaxation) at certain locations on the head, but also with specific patterns that indicate individual illnesses (e.g., ADHD, depression, burnout, etc.).During a training session – in a pleasant atmosphere – the trainee watches a film or listens to music. Whenever the desired activity patterns occur, the trainee receives feedback by the TV picture becoming larger and more visible or the music becoming more audible (positive feedback). Conversely, if undesired activity is detected, the picture becomes smaller or the music becomes quieter (negative feedback). This allows trainees to subconsciously and quickly learn to optimally regulate their brain activity according to the situation.Initial changes typically occur after 5-7 one-hour training sessions, with lasting effects after approximately 15 sessions.
