Abstract:
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 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(all P<0.05, Alphasim Corrected). 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.
