Journal ArticleDOI

Dopaminergic Network Differences in Human Impulsivity

TL;DR: It is found that higher levels of trait impulsivity were predicted by diminished midbrain D2/D3 autoreceptor binding and greater amphetamine-induced DA release in the striatum, which was in turn associated with stimulant craving.
Journal ArticleDOI

Mesolimbic dopamine reward system hypersensitivity in individuals with psychopathic traits

TL;DR: These findings suggest that neurochemical and neurophysiological hyper-reactivity of the dopaminergic reward system may comprise a neural substrate for impulsive-antisocial behavior and substance abuse in psychopathy.
Journal ArticleDOI

Dopaminergic mechanisms of individual differences in human effort-based decision-making.

TL;DR: The authors found that individual differences in DA function in the left striatum and ventromedial prefrontal cortex were correlated with a willingness to expend greater effort for larger rewards, particularly when probability of reward receipt was low.
Journal ArticleDOI

Quantitative pharmacokinetic analysis of DCE-MRI data without an arterial input function: a reference region model

TL;DR: A method is presented that compares the tissues of interest (TOI) curve shape to that of a reference region (RR), thereby eliminating the need for direct AIF measurement and allowing for quantitative assessment of tissue properties without having to obtain high temporal resolution images to characterize an AIF.
