Event-related group averages of the BOLD response time-locked to the onset of somatosensory stimulation. Legend: ancillary brain regions A–F: A = right anterior cingulate cortex (R ACC), B = right insula (R insula), C = right ventral anterior nucleus of the thalamus (R Va Tha), D = right caudate (R caudate), E = right angular gyrus (R BA 40), and F = right dorsolateral prefrontal cortex (R BA 9). Stimulation was applied for a duration of 4 s. The green line represents stimulation applied to the symptomatic body part and the white line to the asymptomatic body part. Error bars represent the standard error.
