The use of magnetic resonance imaging (<jats:styled-content style=\"fixed-case\">MRI<\/jats:styled-content>) in fibromyalgia has allowed for the detection of neural abnormalities, with alterations in brain activation elicited by experimental pain and alterations in resting state connectivity related to clinical pain.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>In this study, we sought to monitor state changes in resting brain connectivity following experimental pressure pain in fibromyalgia patients and healthy controls. Twelve fibromyalgia patients and 15 healthy controls were studied by applying discrete pressure stimuli to the thumbnail bed during <jats:styled-content style=\"fixed-case\">MRI<\/jats:styled-content>. Resting\u2010state functional <jats:styled-content style=\"fixed-case\">MRI<\/jats:styled-content> scanning was performed before and immediately following experimental pressure pain.

Additionally, we observed increased thalamic connectivity to the precuneus\/posterior cingulate cortex, a known part of the default mode network, in patients but not in controls.
