Figure 1 (A) Voxel comparison of degree centrality (DC) in the eye pain (EP) and healthy control (HC) groups: significant differences in DC were observed in the left limbic lobe, right cerebellum posterior lobe, left cerebellum posterior lobe, left inferior temporal gyrus, left inferior parietal lobule, and left precuneus. The red area indicates a higher DC value and the blue color indicates a lower DC value. Multiple comparisons were performed using Gaussian random field theory (z>2.3, column by column correction, P<0.05), P<0.05. (B) Average DC values between EP and HC groups. DC – degree centrality; EP – eye pain; HC – healthy control; L – left; R – right; RCPL – right cerebellum posterior lobe; LCPL – left cerebellum posterior lobe; LLL – left limbic lobe; LITG – left inferior temporal gyrus; LIPL – left inferior parietal lobe; LP – left precuneus.
