Altered Functional Connectivity in Pain-Related Brain Regions and Its Correlation with Pain Duration in Bone Metastasis with Cancer Pain

Figure 2

Functional connectivity matrices of the three groups. Colormap shows values of functional connectivity. CP+: lung cancer patients with bone metastases suffering from cancer pain; CP−: lung cancer patients without pain-related complaints; HC: health controls; DLPFC: dorsal lateral prefrontal cortex; mPFC: medial prefrontal cortex; SI: primary somatosensory cortex; SII: secondary somatosensory cortex; ACC: anterior cingulate cortex; INS: insula; THA: thalamus; AMY: amygdala; PAG: periaqueductal gray; R: right; L: left.
