A feature of multiple neuropsychiatric disorders is motor impulsivity. Recent studies have
implicated serotonin (5-HT) systems in medial prefrontal cortex (mPFC) in mediating …

Impulsivity is widely regarded as a multidimensional trait that encompasses two or more
distinct patterns of behavior, and dopaminergic systems are implicated in the expression of …

We report an experiment testing the hypothesis that impulsive behavior reflects a deficit in
the ability to inhibit prepotent responses Specifically, we examined whether impulsive …

Over the past decade there has been increasing evidence that reduced serotonergic (5HT)
activity, as indexed by cerebrospinal fluid (CSF) 5-hydroxyindoleacetic acid (5HIAA) in living …

Impulsive choice, one aspect of impulsivity, is characterized by an abnormally high
preference for small, immediate rewards over larger delayed rewards, and can be a feature …

The possible involvement of the ascending 5-hydroxytryptaminergic (5HTergic) pathways in
determining the effectiveness of delayed positive reinforcers was investigated using Mazur's …

Impulsivity is a behavioral trait frequently seen not only in drug-addicted individuals but also
in individuals who pathologically overeat. However, whether impulsivity predates the …

Impulsivity is the tendency to act prematurely without foresight. Behavioral and
neurobiological analysis of this construct, with evidence from both animal and human …

Serotonin (5-HT) 2A receptors are known to be involved in prepulse inhibition of the startle
response (PPI), a measure of sensorimotor inhibition that is deficient in schizophrenia …

The purpose of the present study was to investigate whether differences in the function of
monoaminergic systems could account for the variability in attention and impulsive …
