Non‐linear analysis of the sleep EEG

A sleep electroencephalogram was analyzed by non‐linear analysis. The polysomnography of a healthy male subject was analyzed and the correlation dimensions calculated. The correlation dimensions decreased from the ‘awake’ stage to sleep stages 1–3 and increased during rapid eye movement (REM) sleep....

More Information
Summary:A sleep electroencephalogram was analyzed by non‐linear analysis. The polysomnography of a healthy male subject was analyzed and the correlation dimensions calculated. The correlation dimensions decreased from the ‘awake’ stage to sleep stages 1–3 and increased during rapid eye movement (REM) sleep. These results were seen during each sleep cycle. In each sleep cycle, the correlation dimensions decrease for slow wave sleep, and increase for REM sleep.
