Synopsis
The central mechanisms underlying Fibromyalgia syndrome remain undetermined; however, there is increasing evidence to suggest that neurochemical imbalances may play a critical role in the pathophysiology of the condition. The DLPFC is a heterogeneous cortical structure involved in cognitive, affective, and sensory processing of pain known to mediate top down pain modulation. We provide the first evidence of excitatory/inhibitory imbalance within the DLPFC in fibromyalgia syndrome, which we demonstrated to be positively associated with acute/clinical pain measures and the degree of resting state functional connectivity to affective pain circuitry (dorsal anterior cingulate cortex). Together these results suggest a dysregulation of excitation and inhibition in top-down pain modulatory networks with potential pathophysiological implications in pain processing. Furthermore, this evidence provides potential pharmacological and neuromodulatory therapeutic targets for the treatment of fibromyalgia syndrome.
