N2, P3 and the lateralized readiness potential in a nogo task involving selective response priming.

Studied motor inhibition using a hybrid choice-reaction go/no-go procedure involving selective response to clarify whether the N2 or the P3 or both event related potential (ERP) components indicate motor inhibition. 18 Ss (mean age 33 yrs), all being right-handed with normal to corrected-to-normal vision, performed the task. Response time and error measures as well as the lateralized readiness potential indicated that responses were primed by flanker stimuli that were associated with 1 of the 2 possible responses. In no-go trials, selective response priming influenced the N2 amplitude whereas the P3 amplitude was unaffected. Since the N2 appeared irrespective of whether an erroneous response was correctable or not, it is concluded that the N2 reflects either detection or the inhibition of an appropriate tendency to respond.
