Main Field(s) of Research, Abstract
Recent observations indicate that theta activity (5-9 Hz) in waking and slow-wave activity (0.75-4.5 Hz) in sleep represent distinct EEG markers of a common homeostatic sleep process. We conduct studies combining pharmacological, clinical and pharmacogenetic methods, and EEG topography and brain imaging in waking and sleep to investigate putative neurochemical substrates of sleep homeostasis. At present we focus on the adenosinergic system and the roles of adenosine and A1 and A2A receptors in regulating sleep, vigilance and mood in healthy volunteers and psychiatric and neurologic patients (e.g. major depression, Creutzfeldt-Jakob Disease).
Main Fields of Research, Keywords
sleep regulation, EEG spectral analysis, sleep deprivation, vigilance, neuropharmacology, pharmacogenetics, aging, psychiatric and neurological disorders
Special Techniques and Equipment
We apply a multidisciplinary approach including:
· EEG topography in waking and sleep
· DNA molecular-genetic analyses (in collaboration with the Neurology Policlinics, University Hospital Zürich, and the Institute of Medical Genetics, University of Zürich)
· positron emission tomography (in collaboration with the Clinic of Nuclear Medicine, University Hospital Zürich, and the Paul Scherrer Institute (PSI), University of Zürich and ETH)
· pharmacokinetic and pharmacodynamic studies
· neurobehavioral testing
