Source analyses of the second positive component P2 (190–220 ms) in controls and BR participants.

Each sLORETA brain source was obtained from the within-group comparison of painless control condition (corresponding to a virtual zero condition of nocicettive/somatosensory stimulation) with Under Threshold, Threshold or Over Threshold conditions. Cortical activities elicited by each of these three latter stimuli were all significant, and their main generators were located in the dorsal portion of the posterior cingulate cortex (control group) or in the ventral portion of the anterior cingulate cortex (BR group).BA = Brodmann Area; MNI coords = Montreal Neurological Institute coordinates.
