may be more heritable than ERP components giving them a slight edge as endophenotypes [178]. As reviewed in the previous sections, event-related oscillations (EROs) meet the criteria of endophenotypes for alcoholism, as reduced delta, theta and gamma oscillations not only characterize affected alcoholics, but also their relatives, particularly offspring at risk prior to the onset of the illness. Therefore, the use of quantitative ERO endophenotypes provides a powerful strategy for identifying underlying susceptibility genes for developing alcoholism and related disinhibitory disorders.
