The purpose of this study is to develop electronic detectors capable of detecting spindles and conjugate rapid eye movements in the human electroencephalogram EEG and EOG electrooculograph. Period analysis is used as the basis for the detection of spindles defined as rythmic bursts of EEG activity of 12-14 Hz lasting for at least 0.5 second. A phase detection scheme is used to identify the occurrance of conjugate eye movements. Sixteen hours of EEG and EOG data were analyzed using the detectors. The spindle detector exhibited a 90 detection accuracy when used to separate sleep stages 2,3, or 4 and stages 0, 1, or REM. a 68 detection accuracy was achieved by the REM detector.
