Abstract
Previous work has suggested that human subjects engaged in tasks, like the Stroop task, that require response selection utilize the medial f rontal cortex. We used positron emission tomography to measure blood f low changes in a stimulus-response compatibility task designed to maxi mize the demand on response selection processes. We report significant activation in the cingulate sulcus (Brodman's area 32) and a correlat ion of activity in this region with faster response time for an incong ruent stimulus-response task.
