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 ...
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 ...
Neural differences in self-perception during illness and after weight-recovery in anorexia nervosa
(Oxford, 2016-06-27)
Anorexia nervosa (AN) is a severe mental illness characterized by problems with self-perception. Whole-brain neural activations in healthy women, women with AN and women in long-term weight recovery following AN were ...
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 ...
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 ...
Neural computations underlying social risk sensitivity
(Frontiers, 2012-08-02)
Under standard models of expected utility, preferences over stochastic events are assumed to be independent of the source of uncertainty. Thus, in decision-making, an agent should exhibit consistent preferences, regardless ...
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 ...
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 ...
Functional brain network changes associated with maintenance of cognitive function in multiple sclerosis
(Frontiers, 2010-11-22)
In multiple sclerosis (MS) functional changes in connectivity due to cortical reorganization could lead to cognitive impairment (CI), or reflect a re-adjustment to reduce the clinical effects of widespread tissue damage. ...
