We found that different functional connection between fibromyalgia patients and healthy control participants. The status of neuroinflammation may play an important role of influencing functional connection and brain structure may be the part of characteristic feature of fibromyalgia.
Figure 2. (a) (b) (c) The ROIs were selected form DMN, antinociceptive pathway and EAN, respectively. (d) Comparison of DKI parameters showed the significant differences between HC and FM. In FM, decrease MK values shown in DLPFC (HC: 0.655 ± 0.00386, FM: 0.617 ± 0.0178 [*p = 0.032]), ACR (control: 0.967 ± 0.036, FM: 0.919 ± 0.042 [**p = 0.007]), fornix (control: 0.907 ± 0.036, FM: 0.88 ± 0.016 [*p = 0.037]) and genu of corpus callosum (HC: 0.897 ± 0.012, FM: 0.803 ± 0.017 [*p = 0.042]. (e) The MK map of whole brain shows that decrease MK values.
