The effects of alcohol on laboratory-measured impulsivity after l -Tryptophan depletion or loading

Indirect evidence supports a link between serotonergic activity and individual differences in the behavioral response to alcohol, but few studies have experimentally demonstrated that an individual’s biological state can influence the sensitivity to alcohol-induced behaviors.

These findings demonstrate that reduced serotonin synthesis can produce increased impulsivity even among non-impulsive normal controls, and that the behavioral effects of alcohol are, in part, dependent on this biological state.
