Functional MRI group analysis results ((A) and (B): sagittal view; (C) and (D): coronal view; (E) and (F): axial view) in twelve healthy volunteers following Contact Heat Evoked Potential Stimulator stimulation at 51°C, precapsaicin (left panel), and 15 minutes postcapsaicin application (right panel).

Note: The intersection of the blue cross hairs represents the contralateral insular cortex with significant increase in activation postcapsaicin application.
