Abstract (en)
[origin: DE19649991A1] The invention relates to a device and a method for determining sleep profiles. The aim of the invention is to develop a device and a method which automatically generate a sleep stage classification with a grading of approximately 85 % (measured according to the crosscorrelation function between automatically and manually generated sleep profiles) with negligible discomfort to the sleeper caused by additional technical equipment in his or her ordinary environment. The inventive device is characterized in that an electrode strip with a preamplifier (active electrode) working on the basis of a single frontal EEG channel is placed symmetrical to the nose root and is connected to a measuring and analysis unit controlled by a microprocessor and working autonomously. The method is characterized in that the EEG signal is compressed according to characteristics, stored and transmitted to a computer after this preprocessing, and classification according to sleep stages occurs in the computer by means of a population of neuronal networks.
