Abstract
Sleep is not just the oposite of wakefulness. Sleep has its own internal structure with a sequence of light sleep, deep sleep and rapid-eye-movement sleep. The sleep stages are characterized by specific changes in brain waves and in autonomic nervous system functions, such as heart rate and control of breathing. A number of disorders have their origin during sleep. Sleep medicine is dedicated to the diagnosis and therapy of these disorders. Advanced methods of signal analysis are applied to EEG, EOG, EMG, respiratory flow, blood pressure and heart rate to improve diagnosis. These methods are based on digital filtering, spectral analysis and stochastic analysis of signals. Results of these methods can be implemented in new diagnostic devices used in clinical sleep centers.
