Citation: Rokos, A.; Mah, R.; Boshra, R.; Harrison, A.; Choy, T.L.; Abstract: A consistent limitation when designing event-related potential paradigms and interpreting Blain-Moraes, S.; Connolly, J.F. Eliciting and Recording Event Related results is a lack of consideration of the multivariate factors that affect their elicitation and detection Potentials (ERPs) in Behaviourally in behaviorally unresponsive individuals. This paper provides a retrospective commentary on three Unresponsive Populations: A factors that influence the presence and morphology of long-latency event-related potentials—the P3b Retrospective Commentary on and N400.
