title: [Automatic sleep analysis. I. Scoring of parameters].
abstract: EEG, EOG, EMG and motility are recorded and preprocessed by hardware filtering of EEG and hardware detection of sigma spindles, rapid eye movements (REMs) and delta-waves (greater than 45 microV). After AD-conversion calculation of mean values and smoothing, the sleep-wake-process can be represented by the time-curves of 8 parameters: mean amplitudes per epoch (30 s) of EMG, motility and EEG (in the delta- alpha- and beta-band), delta-time (time/epoch of counted delta-waves) and presence or absence of spindles and REMs per epoch. These parameters can be presented graphically or stored for further analysis of sleep stages, sleep structure or sleep periodicity.
