Dopamine supports coupling of attention-related networks
LC Dang, JP O'Neil, WJ Jagust - Journal of Neuroscience, 2012 - Soc Neuroscience
Attentional processing has been associated with the dorsal attention, default mode, and
frontoparietal control networks. The dorsal attention network is involved in externally focused …

Spontaneous eye blink rate (EBR) is uncorrelated with dopamine D2 receptor availability and unmodulated by dopamine agonism in healthy adults
Spontaneous eye blink rate (EBR) has been proposed as a noninvasive, inexpensive
marker of dopamine functioning. Support for a relation between EBR and dopamine function …

Dopamine and the cognitive downside of a promised bonus
It is often assumed that the promise of a monetary bonus improves cognitive control. We show
that in fact appetitive motivation can also impair cognitive control, depending on baseline …

Striatal dopamine influences the default mode network to affect shifting between object features
Cognitive flexibility or the ability to change behavior in response to external cues is
conceptualized as two processes: one for shifting between perceptual features of objects and …

Differential regional decline in dopamine receptor availability across adulthood: Linear and nonlinear effects of age
Theories of adult brain development, based on neuropsychological test results and structural
neuroimaging, suggest differential rates of age‐related change in function across cortical …

Modulation of impulsivity and reward sensitivity in intertemporal choice by striatal and midbrain dopamine synthesis in healthy adults
Converging evidence links individual differences in mesolimbic and mesocortical dopamine

Caudate asymmetry is related to attentional impulsivity and an objective measure of ADHD-like attentional problems in healthy adults
Case–control studies comparing ADHD with typically developing individuals suggest that
anatomical asymmetry of the caudate nucleus is a marker of attention deficit hyperactivity …
