基于光生物调节的睡眠调制效果研究
Study on the effect of sleep modulation based on photobiomodulation
摘要
Abstract
In order to explore the influence of photobiomodulation on the sleep regulation effect,the 860 nm near-infrared light with different frequencies(40,70,110 Hz)were used to induce sleep.Firstly,the electroencephalography(EEG)signals were col-lected for preprocessing,gravity frequency calculation,and time-frequency analysis;secondly,the gravity frequencies and band ener-gies of EEG signals of different frequencies were compared;finally,statistical analysis was performed.The results showed that photobi-omodulation caused the gravity frequency of the brain to be shifted downward,the power of α,θ,and δ bands of the EEG signals was significantly enhanced,and the change of the gravity frequency center of the sleep-related brain regions was significant,which was conducive to fall asleep.This study provides experimental basis and parameter reference for the application of photobiomodulation in in-ducing sleep,is helpful to further understands its mechanism of regulating sleep.关键词
