In Cocaine Dependence, Neural Prediction Errors During Loss Avoidance Are Increased With Cocaine Deprivation and Predict Drug Use
(Elsevier, 2018-08-03)
Background: In substance-dependent individuals, drug deprivation and drug use trigger divergent behavioral responses to environmental cues. These divergent responses are consonant with data showing that short- and long-term ...
Belief about nicotine modulates subjective craving and insula activity in deprived smokers
(Frontiers, 2016-07-13)
Little is known about the specific neural mechanisms through which cognitive factors influence craving and associated brain responses, despite the initial success of cognitive therapies in treating drug addiction. In this ...
Spatiotemporal dissociation of brain activity underlying threat and reward in social anxiety disorder
(Oxford University Press, 2016-10-19)
Social anxiety disorder (SAD) involves abnormalities in social motivation, which may be independent of well-documented differences in fear and arousal systems. Yet, the neurobiology underlying motivational difficulties in ...
Individual Differences in Anticipatory Somatosensory Cortex Activity for Shock is Positively Related with Trait Anxiety and Multisensory Integration
(MDPI, 2016-01-16)
Anxiety is associated with an exaggerated expectancy of harm, including overestimation of how likely a conditioned stimulus (CS+) predicts a harmful unconditioned stimulus (US). In the current study we tested whether ...
Belief about nicotine selectively modulates value and reward prediction error signals in smokers
(NAS, 2015-02-24)
Little is known about how prior beliefs impact biophysically described processes in the presence of neuroactive drugs, which presents a profound challenge to the understanding of the mechanisms and treatments of addiction. ...
Interoception drives increased rational decision-making in meditators playing the ultimatum game
(Frontiers, 2011-04-18)
Human decision-making is often conceptualized as a competition between cognitive and emotional processes in the brain. Deviations from rational processes are believed to derive from inclusion of emotional factors in ...
Longitudinal associations among family environment, neural cognitive control, and social competence among adolescents
(Elsevier, 2017-05-16)
During adolescence, prefrontal cortex regions, important in cognitive control, undergo maturation to adapt to changing environmental demands. Ways through which social-ecological factors contribute to adolescent neural ...
Neuroimaging after mild traumatic brain injury: Review and meta-analysis
(Elsevier, 2014-01-04)
This paper broadly reviews the study of mild traumatic brain injury (mTBI), across the spectrum of neuroimaging modalities. Among the range of imaging methods, however, magnetic resonance imaging (MRI) is unique in its ...
A computational approach to “free will” constrained by the games we play
(Frontiers, 2012-09-27)
Human choice is not free—we are bounded by a multitude of biological constraints. Yet, within the various landscapes we face, we do express choice, preference, and varying degrees of so-called willful behavior. Moreover, ...
Neural cognitive control moderates the association between insular risk processing and risk-taking behaviors via perceived stress in adolescents
(Elsevier, 2018-02-14)
Adolescence is a critical period for the initiation of risk-taking behaviors. We examined the longitudinal interplay between neural correlates of risk processing and cognitive control in predicting risk-taking behaviors ...
