Fifteen right-handed individuals (seven males and eight females, average age 26) participated in a 'go-no-go' exercise. They were asked to press a button on a keyboard but first to indicate what time they were going to perform this action. They were also asked to choose instances in which they stopped before actually pressing the button. When participants decided not to press the button, a specific area of the frontal lobe region of the brain lit up. When participants followed through, however, the area did not light up.
