About 100 years ago, it was possible for the first time to derive electrical activity from the human brain. The neurologist and psychiatrist Hans Berger was able to show that wave-shaped oscillations of different frequencies emanate from the brain. The electroencephalogram (EEG) was invented. Today, researchers know that the precise understanding of these oscillations is the key to the treatment of neurological and psychiatric diseases. There are several approaches to measuring and stimulating brain waves. But researching brain waves is difficult. Ilka Diester, Professor of Optophysiology at the BrainLinks-BrainTools Center at the University of Freiburg, and her research group have developed a method to look at the frequency bands of brain waves individually and to measure brief beta-wave bursts in real time.
