Background Low dopamine D2/3 receptor availability in the nucleus accumbens shell is
associated with highly impulsive behavior in rats as measured by premature responses in a …

Background Impulsivity and novelty preference are both associated with an increased
propensity to develop addiction-like behaviors, but their relationship and respective …

ObjectiveHuman impulsivity is a complex multidimensional construct encompassing
cognitive, emotional, and behavioural aspects. Previous animal studies have suggested that …

Impulsive behavior is thought to reflect a traitlike characteristic that can have broad
consequences for an individual's success and well-being, but its neurobiological basis …

Variation in dopamine receptor levels has been associated with different facets of
impulsivity. To further delineate the neural substrates underlying impulsive action (inability to …

Impulsivity associated with abnormal dopamine (DA) function has been observed in several
disorders, including addiction. Choice impulsivity is the preference for small, immediate …

Dopamine neurotransmission has been consistently associated with individual differences
in impulsive choice. Clinical and preclinical evidence suggests that low striatal dopamine D …

We have previously shown that impulsivity in rats is linked to decreased dopamine D 2/3
receptor availability in the ventral striatum. In the present study, we investigated, using …

Molecular and functional imaging techniques have been used and combined with
pharmacological probes to evaluate the role of dopamine in impulsivity. Overall, strong …

Previous research has identified the nucleus accumbens (NAcb) as an important brain
region underlying inter-individual variation in impulsive behavior. Such variation has been …
