Figure 4.

BOLD fMRI activation during simultaneous EEG. Noxious heat stimuli at 51°C caused BOLD fMRI responses bilaterally in the insula, post-central gyrus, and SMA and contralateral to the site of stimulation in the middle cingulate cortex and pre-central gyrus. Random effect group analysis results (p < 0.05 corrected) are displayed on structural images in neurological convention.
