目的:探讨高度近视(high myopia，HM)和视力正常大学生右侧尾状核全脑功能连接的差异。方法:对25例高度近视(HM组)和27例视力正常被试(normal controls，NC组)进行静息态功能磁共振成像扫描。分别在常规(0.010～0.080 Hz)、慢5(0.010～0.027 Hz)、慢4(0.027～0.073 Hz)频段对比高度近视及正常对照组右侧尾状核及前部亚区、后部亚区全脑功能连接的组间差异。结果:(1)与NC组相比，HM组右侧尾状核与左侧枕中回(MNI：x＝-48，y＝-84，z＝9)、左侧梭状回(MNI：x＝-30，y＝-63，z＝-12)、右侧额中回(MNI：x＝39，y＝12，z＝39)的功能连接增强(n P<0.05，Alphasim校正)。(2)HM组右侧尾状核的全脑功能连接变化主要在前部亚区。(3)HM组右侧尾状核及前部亚区与左侧枕中回的功能连接增强主要体现在慢4频段(n P<0.05，Alphasim校正)。n 结论:高度近视人群右侧尾状核通过增强与视觉及视觉注意脑区的功能连接对视觉感知和视觉注意力起到代偿作用。“,”Objective:To explore the different functional connectivity of right caudate nucleus between adults with high myopia and normal vision controls.Methods:The resting-state functional magnetic resonance imaging(fMRI) data were collected from twenty-five high myopia(HM group) and twenty-seven normal vision subjects(NC group). Right caudate nucleus and their subregions(anterior and posterior subregions included) were used as seeds to perform seed-based functional connectivity (FC)analyses at group level under three different frequency bands: convention (0.010~0.080 Hz), slow-5(0.010~0.027 Hz) and slow-4(0.027~0.073 Hz).Results:(1)Compared with NC group, FC of right caudate nucleus with left middle occipital gyrus(MNI: x=-48, y=-84, z=9), left fusiform gyrus(MNI: x=-30, y=-63, z=-12), and right middle frontal gyrus(MNI: x=39, y=12, z=39) were stronger in HM group(all n P<0.05, Alphasim Corrected). (2)In HM group, these changed FC were mainly detected in the anterior subregion of right caudate nucleus.(3)The increased FC of right caudate nucleus and its anterior subregion with left middle occipital in HM group were mainly reflected in the frequency band of slow-4(alln P<0.05, Alphasim Corrected).n Conclusion:The right caudate nucleus in adults with high myopia may play compensatory roles in visual perception and visual attention by enhancing its functional connectivity with visual and visual attentional brain areas.
