Eeg sleep study trial#
Similar results in an assessor-blinded randomized controlled trial (RCT) design showed a positive impact on sleep perception and quality of life ( Jespersen et al., 2019). In addition, subjects who listened to music had a longer sleep duration, greater sleep efficiency, shorter sleep latency, less sleep disturbance, and less daytime dysfunction as assessed by the Pittsburgh sleep quality index (PSQI) questionnaire ( Tan, 2004). Experiments with subjects listening to music before sleep have revealed that listening to soft music shortens the duration of deep sleep and prolongs the duration of deep sleep ( Chang et al., 2012 Chen et al., 2014). Pharmacological treatment is helpful for people suffering from sleep disorders but also has side effects, and some of these individuals could possibly turn to psychological treatment.Īs a non-pharmacological treatment, music can affect sleep disorders, as shown in a number of studies. Sleep disorders, affecting up to 30% of adults, are a common health problem in our society and may result in fatigue, depression, and problems in daytime functioning ( Chang et al., 2012). SWS brain-wave music could be a safe and inexpensive method for clinical use if confirmed by more data. Furthermore, better sleep quality might be caused by a decrease in the power spectral density of the delta band of EEG and an increase in the FC between the left frontal lobe and the left parietal lobe. In addition, there was a negative correlation between the FC of the left frontal lobe and the left parietal lobe and sleep latency in the SWS group ( r = −0.527, p = 0.064).Ĭonclusion: Slow-wave sleep brain-wave music may have a positive effect on sleep quality, while REM brain-wave music or WN may not have a positive effect. 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. 4Department of Composition, Sichuan Conservatory of Music, Chengdu, ChinaĪim: This study investigated the neural mechanisms of brain-wave music on sleep quality.īackground: Sleep disorders are a common health problem in our society and may result in fatigue, depression, and problems in daytime functioning.3Center for Information in Biomedicine, School of Life Sciences and Technology, University of Electronic Science and Technology of China, Chengdu, China.2The Clinical Hospital of Chengdu Brain Science Institute, MOE Key Lab for Neuroinformation, University of Electronic Science and Technology of China, Chengdu, China.1School of Computer Science, Chengdu University of Information Technology, Chengdu, China.Dongrui Gao 1,2,3†, Siyu Long 3†, Hua Yang 4†, Yibo Cheng 3, Sijia Guo 3, Yue Yu 2, Tiejun Liu 2,3, Li Dong 2,3, Jing Lu 2,3* and Dezhong Yao 2,3*
