![]() ![]() In the network analysis, the functional connectivity (FC), assessed with Pearson correlation coefficients, showed that the connectivity strength decreased between the left frontal lobe (F3) and left parietal lobe (C3) in the SWS group. In the EEG power spectral density analysis, the delta power spectral density in the REM group and in the control group increased, while that in the SWS group decreased. The sleep efficiency in the SWS group was ameliorated. Results: We found that the sleep efficiency increased in the SWS group but decreased in REM and WN groups. EEG and other physiological signals were recorded by polysomnography. The participants listened to rapid eye movement (REM) brain-wave music (Group 1: 13 subjects), slow-wave sleep (SWS) brain-wave music (Group 2: 11 subjects), or white noise (WN) (Control Group: 9 subjects) for 20 min before bedtime for 6 days. Methods: A total of 33 young participants were recruited and randomly divided into three groups. However, the neural mechanisms of brain-wave music on the quality of sleep need to be clarified. Previous studies have shown that brain-wave music generated from electroencephalography (EEG) signals could emotionally affect our nervous system and have positive effects on sleep.
