Abstract:
Recording the sleep-multigraph is an important method for sleep monitoring and research. In this study, after the all-night sleep in six nights being monitored, the process of sleep is shown by EEG complexity and spectrum feature. It can provide a new path for estimating the sleep quality by sleep staging. Especially, the EEG complexity in different sleep stages is studied. The results indicate that the deeper the sleep, the smaller the EEG complexity of whole cortex. This is of significance to the study on sleep biopsychology.
