磁刺激穴位对亚健康失眠的脑网络的影响

Sub-health insomnia seriously affect people's physical and mental health, the quality of life and the effectiveness of the work.Acupuncture has good effects on the treatment of insomnia.But acupuncture exists the problems such as difficulty to quantify.Magnetic stimulation is similar to electrical stimulation on neural mechanism , but magnetic stimulation has more prominent advantages.In this paper, magnetic stimulation acupuncture experiment was carried out on the sub-health insomniacs.Acquisition of EEG signals in the experiment conducted associated characteristics analysis by cross-correlation algorithm,built the resting state and after magnetic stimulation of the brain function network, and studied the characteristic parameters of brain functional networks.Results indicate that magnetic stimulation after acupuncture points, the cross-correlation coefficient in the frontal lobe, the occipital lobe, the temporal lobe and the parietal lobe area are changed significantly (p < 0.05); After stimulation of the brain functional network, average degrees,clustering coefficient and global efficiency are increased, the average path length decreases, and "small world" property is enhanced. Results show that the magnetic stimulation after acupuncture, sub-health insomniac inner regions of the brain connectivity and information communication are improved.
