Serotonergic Mechanisms Underlying Impulsivity And Vulnerability For Stimulant Addiction

Abstract

There is increasing evidence to suggest that impulsivity, a personality trait associated with an increased tendency for premature actions, may predispose individuals to stimulant addiction. The current study employs a non-invasive brain imaging technique in rats – positron emission tomography (PET) – to investigate the implicated role of serotonin (5HT) in impulsivity thereby providing potentially new insights into neural vulnerability mechanisms underlying stimulant addiction.
