The aim of the present study was to test the hypothesis in humans that an oral dose of ethanol would lead to dopamine release in the ventral striatum, including the nucleus accumbens. Six healthy subjects underwent two [\n                    <jats:sup>11<\/jats:sup>\n                    C]raclopride PET scans following either alcohol (1 ml\/kg) in orange juice or orange juice alone. Subjective mood changes, heart rate, and blood\u2010alcohol levels were monitored throughout the procedure. Personality traits were evaluated using the tridimensional personality questionnaire. PET images were co\u2010registered with MRI and transformed into stereotaxic space. Statistical parametric maps of [\n                    <jats:sup>11<\/jats:sup>\n                    C]raclopride binding potential change were generated. There was a significant reduction in [\n                    <jats:sup>11<\/jats:sup>\n                    C]raclopride binding potential bilaterally in the ventral striatum\/nucleus accumbens in the alcohol condition compared to the orange juice condition, indicative of increased extracellular dopamine. Moreover, the magnitude of the change in [\n                    <jats:sup>11<\/jats:sup>\n                    C]raclopride binding correlated with the alcohol\u2010induced increase in heart rate, which is thought to be a marker of the psychostimulant effects of the drug, and with the personality dimension of impulsiveness. The present study is the first report that, in humans, alcohol promotes dopamine release in the brain, with a preferential effect in the ventral striatum. These findings support the hypothesis that mesolimbic dopamine activation is a common property of abused substances, possibly mediating their reinforcing effects.
