Laboratory description

The sleep laboratory at the University Hospital of Geneva has as the main mission the diagnosis and treatment of sleep disorders.

The current research projects concern insomnia and excessive daytime sleepiness, by studying oscillatory neuronal activity.

The main techniques used for projects are EEG devices and psycho-physiological tools.


Technical Capabilities and areas of expertise

The sleep laboratory has the infrastructure for clinical and research polysomnographic studies. In addition it has EEG devices for clinical and research (high resolution EEG).
The laboratory team has developed expertise on imaging, and EEG signal processing.


Additional Descriptors, Keywords

Attention, aging, depression, sleep apnea.
