Belief about nicotine modulates subjective craving and insula activity in deprived smokers
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 ...
Subsecond dopamine fluctuations in human striatum encode superposed error signals about actual and counterfactual reward
In the mammalian brain, dopamine is a critical neuromodulator whose actions underlie learning, decision-making, and behavioral control. Degeneration of dopamine neurons causes Parkinson’s disease, whereas dysregulation of ...
Irrational exuberance and neural crash warning signals during endogenous experimental market bubbles
Groups of humans routinely misassign value to complex future events, especially in settings involving the exchange of resources. If properly structured, experimental markets can act as excellent probes of human group-level ...
Simulating future value in intertemporal choice
The laboratory study of how humans and other animals trade-off value and time has a long and storied history, and is the subject of a vast literature. However, despite a long history of study, there is no agreed upon ...
Belief about nicotine selectively modulates value and reward prediction error signals in smokers
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. ...
Biosensor Approach to Psychopathology Classification
We used a multi-round, two-party exchange game in which a healthy subject played a subject diagnosed with a DSM-IV (Diagnostic and Statistics Manual-IV) disorder, and applied a Bayesian clustering approach to the behavior ...
