Abnormal Functional Connectivity of Insular in Primary Insomnia Based on Resting-state fMRI Study
摘要
Abstract
[Objective] To explore the activity aberration of primary insomnia (PI) patients with resting-state fMRI.[Methods]Resting-state fMRI datasets of 60 PI and 60 healthy controls were acquired.We investigated the cortical connectivity patterns of the insula in PI and independent-sample t-test were used to compare the brain activity abnormalities between two groups.[Results] In PI,we found enhanced connectivity between left insular with the left middle cingulate cortex,the Frontal_Sup_Media and right Parietal_Inf,as well as decreased connectivity with the left precentral gyrusand the right fusiformgyrus (P ＜ 0.05).The right insular show increased FC with the right middle cingulate cortex,the right fusiform gyrus and the right middle frontal gyrus,as well as decreased FC with the right precentral gyrus and the right middle temporal gyrus (P ＜ 0.05).[Conclusion] This study provides additional evidence of brain functional integration alterations in PI.Those may help us understand the possible neural mechanisms of PI.关键词
