in moderate doses produced a significant deterioration in detection of erroneous responses (ERN). Another study suggested that later stages of outcome processing were affected by alcohol, as indicated by reduced P300 to loss feedback (Euser et al., 2011). Motor preparation was evaluated using the lateralized readiness potential (LRP) in trials where the response had to be withheld (No-Go); the LRP was significantly higher postalcohol ingestion and the movement-related mu rhythm was also significantly attenuated, suggesting a premature activation of the motor system (Marinkovic et al., 2000). This also provides evidence for enhanced motor impulsivity that may be part of the conceptual framework of the response inhibition model.
