Fibromyalgia (FM) is a medical disorder characterized by chronic widespread pain, a heightened and painful response to pressure. Currently, no investigation is available for identifying the power spectral density of low frequency BOLD fluctuations during resting-state functional magnetic resonance imaging (rs-fMRI) while recent study evaluated functional connectivity of low frequency fluctuation in FM patients. Using seed-based analysis of low frequency BOLD fluctuations in pain related networks, our results demonstrated (1) the medial and lateral pain networks of slow fluctuation BOLD signal during rs-fMRI and (2) the differences in the power spectral density within pain-related networks between FM patients and healthy controls.
