TLDR
Nogo stimuli elicited larger negative components at the frontal electrode sites, and larger late-positive components and smaller Slow Wave components then degraded stimuli, but these amplitude-differences were seen more clearly in the nogo than in the go conditions.About:

Updating P300: An Integrative Theory of P3a and P3b
TL;DR: The empirical and theoretical development of the P300 event-related brain potential is reviewed by considering factors that contribute to its amplitude, latency, and general characteristics.
Journal ArticleDOI
Is the P300 component a manifestation of context updating
TL;DR: The amplitude of the P300 component is controlled multiplicatively by the subjective probability and task relevance of eliciting events, whereas its latency depends on the duration of stimulus evaluation as mentioned in this paper.
Journal ArticleDOI
Influence of cognitive control and mismatch on the N2 component of the ERP: a review.
TL;DR: This work focuses on paradigms that elicit N2 components with an anterior scalp distribution, namely, cognitive control, novelty, and sequential matching, and argues that the anterior N2 should be divided into separate control- and mismatch-related subcomponents.
Journal ArticleDOI
The neural basis of error detection: conflict monitoring and the error-related negativity.
TL;DR: It is concluded that the ERN can be explained in terms of response conflict and that monitoring for conflict may provide a simple mechanism for detecting errors.
Journal ArticleDOI
On the utility of P3 amplitude as a measure of processing capacity
TL;DR: The utility of P3 amplitude as a sensitive and diagnostic measure of processing capacity remains limited because the two principal task variables that have been used to manipulate capacity allocation have opposite effects on the amplitude.

A metric for thought: a comparison of P300 latency and reaction time
Gregory McCarthy,Emanuel Donchin +1 more
TL;DR: It is confirmed that the latency of the P300 component of the human event-related potential is determined by processes involved in stimulus evaluation and categorization and is relatively independent of response selection and execution.

On the Dependence of P300 Latency on Stimulus Evaluation Processes
TL;DR: The present experiments confirm that P300 latency can be used as a measure of the timing of stimulus evaluation processes that is relatively independent of response selection and execution and indicate that the P300 is sensitive to the ease with which a target stimulus can be discriminated from noise.

ERPs to response production and inhibition.
Adolf Pfefferbaum,Adolf Pfefferbaum,Judith M. Ford,Judith M. Ford,Barbara J Weller,Barbara J Weller,Bert S. Kopell,Bert S. Kopell +7 more
TL;DR: Three experiments investigating the effects of response production and inhibition on the N2 and P3 components of the ERP are reported, finding the sensitivity of these findings to the orientation of the symbols instructing the subjects to respond or withhold the response was robust.

Topography of the human motor potential
TL;DR: The MP field distribution was shown to be compatible with its generation by a source of comparable size to the excitable motor cortex and shows a somatotopic distribution for contractions of various muscles similar to that obtained by cortical stimulation.
