There has been plenty of research concerning the representation of voluntary action in the human brain. However, the question how we represent the voluntary omission of an action has been largely neglected. Therefore this study aimed at investigating the representation of intentionally not doing something by means of event-related-potentials (ERPs). Intentional no-actions elicit similar evoked potentials as intentional actions which leads us to assume that the voluntary intention not the overt no-action is the characteristic feature of intentional no-action. Beyond that we reveal differences between intentional no-actions and instructed no-actions which resemble the typical N2 and P3 augmentation usually seen for NoGo trials in Go/NoGo paradigms, with the difference that the intentional no-action ERP takes the place of the typical Go ERP.
