Electroencephalography (EEG) has been used in neurological and neuropsychological research since the 1920s to measure the electrical activity of the brain by recording voltage fluctuations on the surface of the head. With the help of these measurements, we can study how the human brain processes speech and acoustic signals or what traces are left in the brain by chronic tinnitus or learning a new language.

The EEG laboratory of the University of Zurich in Scheuchzerstrasse offers all the equipment for neurofeedback training and also a quiet and relaxed atmosphere. |

Thanks to the latest EEG & software technology, you can concentrate on the game while trained neurofeedback therapists record your brain waves in real time and determine the level of difficulty of the game.Neurofeedback is characterised by the measurement, analysis and modulation of brain waves in real time. Similar to the operant conditioning model, the neurofeedback process uses different visual or auditory stimuli ("feedbacks" such as games, movies, music) to reinforce the occurrence of preferred brainwave patterns and reduce undesired brainwave patterns. |

The electromagnetically isolated EEG chamber provides an accurate way to study brain waves for research purposes. |
We can analyse the recorded data using various established evaluation methods (event-correlated brain potentials, source estimation, time-frequency analyses, microstate analyses, wavelet analyses, topographic dissimilarity, etc.). This procedure is non-invasive and without any risks for the participants. For our measurements, we use a 128-channel system from the company Biosemi and a shielded chamber from the company Diatec.
Based on the current state of research and our own data, we develop specific neurofeedback protocols based on source estimation in our laboratory. Source estimation in real time allows us, in contrast to conventional neurofeedback methods, to precisely target and modulate the brain regions and networks in question. The necessary hardware and software is developed by the company Eeginfo ( homepage). We work closely with Eeginfo in the research and development of this method.

In addition to expertise and staff, the University Hospital Zurich also supports tinnitus research with additional laboratory space. |

The laboratory rooms provide opportunities for a variety of imaging procedures, such as EEG examinations, as well as the possibility of detailed audiometric tests. |
