Activation in mesolimbic and visuospatial neural circuits elicited by smoking cues: evidence from functional magnetic resonance imaging.
(Am J Psychiatry, 2002-06)OBJECTIVE: The authors sought to increase understanding of the brain mechanisms involved in cigarette addiction by identifying neural substrates modulated by visual smoking cues in nicotine-deprived smokers. METHOD: Event-related ... -
Association between the oxytocin receptor (OXTR) gene and mesolimbic responses to rewards.
(Mol Autism, 2014-01-31)BACKGROUND: There has been significant progress in identifying genes that confer risk for autism spectrum disorders (ASDs). However, the heterogeneity of symptom presentation in ASDs impedes the detection of ASD risk genes. ... -
Cocaine dependence does not contribute substantially to white matter abnormalities in HIV infection.
(Journal of neurovirology, 2017-06)This study investigated the association of HIV infection and cocaine dependence with cerebral white matter integrity using diffusion tensor imaging (DTI). One hundred thirty-five participants stratified by HIV and cocaine ... -
Cognitive and neural contributors to emotion regulation in aging.
(Social cognitive and affective neuroscience, 2011-04)Older adults, compared to younger adults, focus on emotional well-being. While the lifespan trajectory of emotional processing and its regulation has been characterized behaviorally, few studies have investigated the underlying ... -
Cortical Brain Activity Reflecting Attentional Biasing Toward Reward-Predicting Cues Covaries with Economic Decision-Making Performance.
(Cereb Cortex, 2016-01)Adaptive choice behavior depends critically on identifying and learning from outcome-predicting cues. We hypothesized that attention may be preferentially directed toward certain outcome-predicting cues. We studied this ... -
Mapping the semantic structure of cognitive neuroscience.
(J Cogn Neurosci, 2014-09)Cognitive neuroscience, as a discipline, links the biological systems studied by neuroscience to the processing constructs studied by psychology. By mapping these relations throughout the literature of cognitive neuroscience, ... -
Nucleus accumbens mediates relative motivation for rewards in the absence of choice
(Frontiers in Human Neuroscience, 2011-01-01)To dissociate a choice from its antecedent neural states, motivation associated with the expected outcome must be captured in the absence of choice. Yet, the neural mechanisms that mediate behavioral idiosyncrasies in motivation, ... -
Rapid brain responses independently predict gain maximization and loss minimization during economic decision making.
(J Neurosci, 2013-04-17)Success in many decision-making scenarios depends on the ability to maximize gains and minimize losses. Even if an agent knows which cues lead to gains and which lead to losses, that agent could still make choices yielding ... -
Resolving response, decision, and strategic control: evidence for a functional topography in dorsomedial prefrontal cortex.
(J Neurosci, 2009-10-21)The dorsomedial prefrontal cortex (DMPFC) plays a central role in aspects of cognitive control and decision making. Here, we provide evidence for an anterior-to-posterior topography within the DMPFC using tasks that evoke ... -
Scan-rescan reliability of subcortical brain volumes derived from automated segmentation.
(Hum Brain Mapp, 2010-11)Large-scale longitudinal studies of regional brain volume require reliable quantification using automated segmentation and labeling. However, repeated MR scanning of the same subject, even if using the same scanner ...
