The Electroencephalography (EEG) platform at Campus Biotech combines equipment and skills that make it possible to carry out experiments that require the technique.
Invented in 1920 by Dr. Hans Berger, EEG is still a method of choice for exploring brain activity. The idea is simple: record the electrical activity generated by the neuronal cells using sensors placed under the scalp, in the same way as tension is measured in an electrical circuit. The applications are numerous and at the forefront of research in clinical or cognitive neuroscience.
In effect, the remarkable temporal resolution of the EEG (down to one millisecond) makes it possible to analyse extremely fast cognitive processes, glimpse very brief transitory pathological activities or even measure brain micro-states evolving at very high speed. Furthermore, as the EEG directly measures brain activity, there is essentially almost no delay between a neuron being activated and observed. This opens up the channel to the vast range of applications for Brain Computer Interfaces (BCI) .
Modern EEG recording systems now have very little to do with the rudimentary device developed by Dr. Berger. The EEG platform at the Campus Biotech is equipped with a variety of ultra modern systems so that scientists can use the system that is most suitable for their research.
- High density EEG systems with 256 electrodes for high precision mapping of brain activity
- MRI compatible EEG systems for simultaneous MRI/EEG recordings, offering both the excellent spatial resolution of MRI and the high temporal precision of EEG
- Highly autonomous and movement-resistant portable EEG systems for mobile recordings (sporting activities, virtual reality etc.)
- "Active electrode" EEG system for recordings outside of environments protected from electromagnetic noise
The platform also offers space dedicated to the use of its equipment. This includes recording rooms protected against external electromagnetic noise (Faraday cage) and equipped with the material required for conducting neuroscience experiments.
The EEG is often combined with other methods and that is why the platform works in close collaboration with the other human neuroscience platforms at Campus Biotech, whether for simultaneous MRI/EEG recordings, monitoring physiological signals for EEG recordings within the clinical research platform or virtual reality EEG recordings.
This platform is under the scientific supervision of Professor Christoph Michel (UNIGE) and Professor José del R. Millán (EPFL/CNP).
It is managed by Dr. Gwenael Birot.
