yet no ERO/ERPs studies done in alcoholics during/after the administration of anti-craving/anti-dependence medications, such as acamprosate, naltrexone, etc., a few resting EEG studies in animals [210-212] and in humans [213-215] found EEG alterations after administration of these drugs. While animal studies indicated a slowing or reduction of frequency, human studies were equivocal. Future electrophysiological research (especially ERP and ERO studies) should further investigate this important aspect.
