Analysis of Human Cerebral Function and Brain Network under Sleep Deprivation
摘要
Abstract
Human cerebral MRI data are acquired under resting state and sleep deprivation, the time sequenceof functional magnetic resonance is extracted via wavelet transform, and the relativity of 116 human brain regions iscalculated. This paper finds that human brain function connection has obvious change by comparing it with restingstate under sleep deprivation, i. e., connection strength, clustering coefficient, feature path length, networkefficiency and small⁃world feature have significant change. Under sleep deprivation, cerebral regional pointefficiency change activation in brain is increased, brain activation compensation is enhanced, however, incerebellum region, point efficiency is significantly decreased, the impact on the number of cerebellum region ismore than that of brain, which indicate that the effect of sleep deprivation on cerebellum regions is more obviousthan that of brain regions.关键词
