Adenosine A 2A receptors (A2ARs) are thought to interact negatively with the dopamine D 2
receptor (D2R), so selective A2AR antagonists have attracted attention as novel treatments …

Decision-making involves frontolimbic and dopaminergic brain regions, but how prior choice
outcomes, dopamine neurotransmission, and frontostriatal activity are integrated to affect …

Methamphetamine use disorder is associated with striatal dopaminergic deficits that have
been linked to poor treatment outcomes, identifying these deficits as an important therapeutic …

Motor response inhibition is mediated by neural circuits involving dopaminergic transmission;
however, the relative contributions of dopaminergic signaling via D 1 - and D 2 -type …

The purpose of this study was to evaluate the mechanisms of age‐related decline of
dopamine transporter (DAT) and dopamine D 2 ‐like receptor (D 2 R) densities in the human …

Neutron-production double-differential cross sections were measured for the spallation reaction
induced by 0.8, 1.5 and 3.0GeV protons on C, Al, Fe, In and Pb targets. The experiments …

Background: Individuals with substance use disorders typically exhibit a predilection toward
instant gratification with apparent disregard for the future consequences of their actions. …

Relative values of differential cross sections (DCS) are measured by the crossed-beam
method. Two cylindrical-mirror energy analysers are employed. One of them is moved to detect …

Background: In clinical practice, equivocal findings are inevitable in visual interpretation of
whether amyloid positron emission tomography (PET) is positive or negative. It is therefore …

Previous studies of aging effects on fluorine-18-labeled fluorodeoxyglucose ( 18 F-FDG)
distribution have employed cross-sectional designs. We examined aging effects on 18 F-FDG …
