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. ...
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 ...
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. ...
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 ...
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 ...
Predictability Modulates Human Brain Response to Reward
(Society for Neuroscience, 2001-04-15)
Certain classes of stimuli, such as food and drugs, are highly effective in activating reward regions. We show in humans that activity in these regions can be modulated by the predictability of the sequenced delivery of ...
Aging into Perceptual Control: A Dynamic Causal Modeling for fMRI Study of Bistable Perception
(Frontiers Media S.A., 2016-03-31)
Aging is accompanied by stereotyped changes in functional brain activations, for example a cortical shift in activity patterns from posterior to anterior regions is one hallmark revealed by functional magnetic resonance ...
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 ...
Aging into Perceptual Control: A Dynamic Causal Modeling for fMRI Study of Bistable Perception
(Frontiers, 2016-03-31)
Aging is accompanied by stereotyped changes in functional brain activations, for example a cortical shift in activity patterns from posterior to anterior regions is one hallmark revealed by functional magnetic resonance ...
Neuroimaging Strategies Addressing Challenges in Using fMRI for the Children with Cerebral Palsy
(Scientific Research Publishing Inc., 2018-05-17)
Aim: This study sought to develop a process and methodology that could be a useful clinical and research tool for successfully completing functional magnetic resonance imaging (fMRI) scanning in children with Cerebral ...
