Objective Assessment of Cognitive Factors Involved in Visceral Perception by Using Event-Related Cerebral Evoked Responses to Esophageal Target Stimulation in Man

Evoked potential (EP) studies provide an objective measure of the neural pathways involved with perception of gastrointestinal stimulation. The effects of cognitive factors, such as anticipation or awareness, on EP responses are not known. We compared the EP response to esophageal electrical stimulation with the cortical activity associated with target… (More)
