Laboratory description

Our group is involved in research on sleep regulation with emphasis on the interaction between the circadian clock and sleep regulatory mechanisms. Research is mainly approached in rats and mice applying long-term recordings of the electroencephalogram (EEG) sometimes in combination with neuronal activity in the suprachiasmatic nucleus (SCN) of the hypothalamus, the location of the circadian clock in mammals, on the multi-unit and single-unit level together with behavioral techniques to record daily rest-activity patterns.
