Abstract:
Such representations may include the average frequency value of electroencephalographic signals, the logarithm of the power of electromyographic signals, and eye movement indications from electrooculographic signals. Criteria for dividing the records of such representations in the system into stages of sleep can be set by a system operator reviewing these records based on accepted stage definition rules. In addition, transient events such as sleep spindles, etc. , in these records can be selected therefrom by criteria set by the system operator also based on accepted rules therefor.
