had posterior maxima, especially in the ORN component (Fig. 5); 4) sLORETA analysis showed that alcoholics, compared to controls, had a significantly decreased ORP current density at cingulate gyrus and less negative ORN current density at primary sensory and motor areas (Fig. 6); 5) comparison of behavioral measures indicated that alcoholics showed a significantly higher impulsivity non-planning category of BIS impulsivity, and there was also a tendency towards higher motor impulsivity and behavioral risk-taking features among alcoholics; and 6) Some of the behavioral/impulsivity dimensions appeared to have high correlations with ERP measures, although alcoholics and controls differed in the nature of these correlations.
