静息态亚健康失眠脑功能网络分析

In this paper, nine subjects in sub-healthy state with insomnia and nine healthy subjects were chosen according Pittsburgh Sleep Quality Index to participate in the experiment. 64-channel electroencephalography (EEG) signals of nine subjects in sub-healthy state with insomnia and nine healthy subjects in the resting state were recorded using 128-channel EEG analyzer. We researched the specific differences between subjects in sub-healthy state with insomnia and healthy subjects based on the analysis of EEG synchronism, the construction and analysis of brain functional networks, which provides new ideas for quantitative diagnosis of sub-healthy state with insomnia. The results showed that the EEG synchronism of subjects in sub-healthy state with insomnia was reduced, the edges of the brain functional network were decreased, so the brain activity was reduced.
