The present study examined the correlation between pain perception and the cardiac-cycle related brain evoked potential, termed the heartbeat-evoked potential (HEP). Electroencephalogram (EEG) and Lead-II electrocardiogram (ECG) were simultaneously recorded from 12 subjects. Prominent HEP was observed mainly over frontal-central-parietal regions in both no-task control and no-pain control conditions, while it was largely suppressed in cold pain condition elicited by hand immersion in 10oC cold water. The suppression of HEP in cold pain condition implies that the HEP could represent a neural correlate of pain perception.
