title: Theta and delta band activity explain N2 and P3 ERP component activity in a go/no-go task.
abstract: OBJECTIVE
  Recent work indicates that the feedback negativity and P3 components from gambling feedback tasks can be understood as mixtures of functionally distinct processes occurring separately in theta and delta frequency bands. The current study was conducted to assess whether dissociable processes occurring in the theta and delta bands would similarly account for activity underlying N2 and P3 components in a go/no-go task.
  
  
  METHODS
  The current study measured EEG signals from 66 participants during a go/no-go task, and a time-frequency principal components analysis decomposition approach was used to extract theta and delta measures from condition averages.
  
  
  RESULTS
  Theta and delta measures separately increased in relation to response inhibition, and were uniquely related to the N2 and P3 components, as predicted.
  
  
  CONCLUSIONS
  Findings support the view that the theta and delta measures indexed separable processes related to response inhibition, and better indexed the processes underlying N2 and P3 components in this go/no-go task.
  
  
  CONCLUSIONS
  Theta and delta measures may index separable functional processes across other common ERP tasks, and may represent an improved target for research relative to standard time-domain components.
