N2 - A real-time rapid eye movement (REM) sleep detection system has been developed, which is composed of a portable digital recorder and a personal computer (PC) connected with a USB interface. The recorder amplifies, filters and samples the polygraphic signals such as electromyogram (EMG), electrooculogram (EOG), and electroencephalogram (EEG), and then sends them to the PC. The PC enables the real-time detection of REM sleep by heuristically evaluating the EMG activities, number of rapid eye movements, and the power spectral density of the EEG for every 10 s epoch. The performance of the developed system has been assessed by comparing the scores with those of off-line processing.
