Taken together, these studies suggest an ongoing process of refinement in ascertaining binge drinking, and as this is still in development, a definitive picture of electrophysiological deficits is yet to emerge. Binge drinking appears to be associated with a specific pattern of EEG activity (increased fast beta) in young adults that may reflect the future development of AUDs. The ERP measures are equivocal, particularly in the context of response inhibition; however a few studies do indicate deficits in perceptive as well as decisional processes, as reflected in decrements in early (P1, N1) and late (N2, P3b) ERP components, as well as changes in frontal sources of these activities.
