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.

and left and right EAN. (b) FM showed significant higher activation
in DMN, antinociceptive network and EAN.
