So-called binaural beats are said to be a miracle cure for relaxation and concentration. Gereon Nelles, board member of the Federal Association of German Neurologists, considers this to be dubious – but the way it works is not impossible.
Mr. Nelles, you are a board member of the Professional Association of German Neurologists. There are all sorts of promises on the Internet that certain sounds, so-called binaural beats, can virtually conjure up states of consciousness such as concentration or relaxation. When you hear such sounds, it is said to affect your brain waves and put you in that state. From the beginning: What are brain waves?
So, in neurology, by brain waves we mean the electrical activity of the brain. The nerve cells essentially work by transmitting small electrical impulses. We can measure this with electrodes that are attached to the head. This creates a wave image.
