Pain-related SEP and fMRI one month after cardiac arrest. Left side: Three bilateral SEP channels: Fpz - C3'/C4', left Erb's/right Erb's - C3'/C4', Fpz- right Erb's/left Erb's. Note the appearance of MLCEP (P50/N60), which is more evident on the right side. Right side: Four fMRI scans at 99% sensitivity during the 50 mAmp electrical stimulation. Note the activation of bilateral primary, secondary, motor, posterior cingulated, and cerebellar cortex.
