According to the standard 30 cases of primary insomnia, 30 cases were in the standard of normal health control (Healthy control, HC), and the sex of group HC was the same as that in the PI group. Before the MRI scan, all the subjects were measured by the clinical scale, including the Pittsburgh sleep mass index (Pittsburgh Sleep Quality Index, PSQI), and the Hamilton Depression Scale (Hamilton Depression Scale, HAMD), the Hamilton Anxiety Scale (Hamilton Anxiety Scale, HAMA) and the spatial working memory scale. The magnetic resonance scanning sequence included magnetic resonance conventional scan, magnetic resonance resting state brain functional imaging scan, and dual sample t test for PI, HC group clinical scale. Seed points, using SPM8 and Rest software to pretreat magnetic resonance brain function data, compare PI, HC group, resting state brain default network and their differences. Results: 1 PI, HC group clinical data analysis results of group 1.1 PI and HC group, PSQI, HAMD, HAMA, spatial working memory scale Compared with the depressive group, there was no significant difference in PSQI tenor, HAMA,.2 PI, the resting state brain default network MRI results in HC group 2.1 PI, HC group resting state brain default network, two groups and PCC functional connection brain areas mainly including cingulate gyrus, prefrontal lobe, bilateral parietal cortex, parahippocampal gyrus and lateral temporal lobe,.2.2 PI in occipital cortex, HC group contrast The ability to connect the enhanced brain area included bilateral upper frontal gyrus and bilateral cingulate gyrus; PI group and PCC functional connection weakened brain area including left occipital lobe, left parahippocampal gyrus, right temporal lobe.2.3 PI moderate depression group compared with mild depression group, PI moderate depression group and PCC functional connection enhanced brain area including middle cingulate gyrus, right frontal gyrus, PI. In the moderate depression group, the functional connection with PCC weakened the brain area, including the left parahippocampal.3. Conclusion 1, the primary insomnia group had the basic clinical characteristics of sleep disorders and cognitive dysfunction; anxiety and depression were the main associated affective disorders in the patients with primary insomnia; there was no significant correlation between the degree of primary insomnia with depression and the degree of anxiety; 2, The primary insomnia group had the brain default network, the primary insomnia group had the brain default network abnormality, which revealed that the primary insomnia group had obvious memory decline cognitive impairment and emotional regulation dysfunction, and the clinical scale had empty work memory cognitive decline, depression and anxiety. The abnormal phase of the mood was.3, and the middle cingulate gyrus was a sign of depression related brain area, related to the degree of depression. The damage degree of the hippocampus was related to the degree of insomnia. The second part of the primary insomnia patients and the spatial working memory related neural network fMIRI research purposes: this experiment uses magnetic resonance brain power imaging technique and the resting state brain function connection. In order to study the function of the right apical lobule (BA7/5) in the empty working memory, the function of the right apical lobule (BA7/5) in the empty work memory is studied. A certain scientific basis is provided for the pathogenesis of neurophysiology. Methods: the experimental group standard, the number of the experimental group and the clinical scale are the same as the first part. The second part of the experiment is carried out on the basis of the first part. The magnetic resonance spatial task state fMRI data scanning is in the first part of the conventional magnetic resonance scanning, the magnetic resonance resting state brain. After functional imaging, the process of brain function data preprocessing is the same as the first part. First, the right apical lobule is the seed point, and the resting state of group PI and HC is compared with its related neural networks and differences, and then the two groups of neural networks and their difference analysis are analyzed and analyzed in the space work task state, which is the cognitive impairment of clinical primary insomnia. Results: 1: 1 on the right top superior lobule (BA7/5) as the seed point, resting state and spatial working memory function neural network study of the 1.1 HC group resting state and the right parietal lobule (BA7/5) functional connection related main brain areas including: bilateral parietal cortex, bilateral frontal cortex, bilateral temporal cortex, bilateral occipital lobe The cortex, right cerebellar hemisphere, right parahippocampal gyrus, the strength and scope of the right hemispherical connection are higher than that of the left hemisphere.1.2 PI group and the resting state and the right superior lobule (BA7/5) functional connection, including the lateral parietal cortex, bilateral frontal cortex, bilateral temporal cortex, bilateral occipital cortex, bilateral cerebellar hemisphere, left anterior lobe / left anterior lobe. The left posterior cingulate gyrus; the strength and scope of the right hemispherical connection were higher than that in the left hemisphere.1.3 PI.HC group. The functional connection between the PI group and the right upper parietal lobule (BA7/5) enhanced brain region mainly included bilateral frontal lobes, bilateral central posterior gyrus, and left anterior wedge lobe: the functional connection weakened the brain area including the right cerebellar hemisphere, left bean nucleus and right parahippocampal. Gyrus, right occipital lobe cortex.2 PI, HC group space working memory task state fMRI imaging results 2.1 HC group vacant task activation brain area mainly include: bilateral parietal lobe, bilateral frontal lobe, bilateral temporal lobe, bilateral occipital lobe, bridge brain, midbrain, cerebellar hemisphere, bilateral thalamus, bilateral insula lobe.2.2 PI group space working task activation brain area mainly include: Double The lateral parietal cortex, bilateral frontal cortex, bilateral temporal cortex, bilateral occipital cortex, bilateral insula, bilateral cerebellar hemisphere, left parahippocampal gyrus, left thalamus, left thalamus, right bridge brain.2.3 PI, HC group were compared. The activation of task state in the PI group enhanced the main brain areas including left temporal lobe, left occipital lobe, right frontal lobe, and PI group and task memory task. The activation of the brain consists of the left parahippocampal gyrus, the right parahippocampal gyrus, bilateral cortex of the lobe, the lateral frontal cortex, and the upper lobule on the bilateral top. Conclusion: 1, the task of working memory is completed by several brain regions, with a specific neural network, including bilateral parietal cortex, bilateral frontal cortex, bilateral temporal cortex, bilateral cortex, bilateral temporal cortex. Occipital cortex, bilateral Island leaves, cerebellar hemispheres, bridge brain, thalamus and other brain regions; bilateral parietal lobe is the main functional brain area for working memory; empty task memory task has the right hemisphere superiority. 2, the right parietal lobule (BA7/5) is the seed point function connection resting state neural network, and the main neural network in the clear brain area of space work task. The right parietal lobule (BA7/5) is the core component of the empty work memory network, and it can be used as the seed point for spatial working memory. It can be used as the seed point for spatial working memory.3. The patients with primary insomnia have the abnormal working memory related neural network, which reveals the decline in the clinical spatial working memory of the patients with primary insomnia, the cognitive impairment and the memory decline.
