Operant matching as a Nash equilibrium of an intertemporal game.
29 Sep 2009 Over the past several decades, economists, psychologists, and neuroscientists have conducted experiments in which a subject, human or animal, repeatedly chooses between alternative actions and is rewarded based on choice history. While individual ...

A neurocomputational model for cocaine addiction.
29 Sep 2009 Based on the dopamine hypotheses of cocaine addiction and the assumption of decrement of brain reward system sensitivity after long-term drug exposure, we propose a computational model for cocaine addiction. Utilizing average reward temporal ...

29 Sep 2009 The capability of cocaine cues to generate craving in cocaine-dependent humans, even after extended abstinence, is modeled in rats using cue reinstatement of extinguished cocaine-seeking behavior. We investigated neural activity associated with ...

28 Sep 2009 To make economic choices between goods, the brain needs to compute representations of their values. A great deal of research has been performed to determine the neural correlates of value representations in the human brain. However, it is still ...

8 Sep 2009 Both conscious and unconscious memory mechanisms contribute to the rewarding effects of nicotine and other drugs of abuse. In this issue of Neuron, Tang and Dani use in vivo measures of synaptic plasticity in freely moving mice to link ...

Orexin A/hypocretin-1 selectively promotes motivation for positive reinforcers.
7 Sep 2009 Orexin A/hypocretin-1 (oxA/hcrt-1) is known to be a modulator of dopamine-dependent neuronal activity and behaviors. However, the role of this system in driving motivated behaviors remains poorly understood. Here, we show that orexin/hypocretin ...

Negative reinforcement eating expectancies, emotion dysregulation, and symptoms of bulimia nervosa.
30 Aug 2009 OBJECTIVE: Research suggests that emotion dysregulation or difficulties in the modulation of emotional experience constitute risk for eating disorders. Recent work has also highlighted the role of certain eating-related cognitions, specifically ...

The Gambling Craving Scale: Psychometric validation and behavioral outcomes.
30 Aug 2009 Although craving is an important feature of problem gambling, there is a paucity of research investigating craving to gamble. A major stumbling block for craving research in gambling has been the lack of a methodologically sound, multidimensional ...

Learning to become an expert: reinforcement learning and the acquisition of perceptual expertise.
30 Aug 2009 To elucidate the neural mechanisms underlying the development of perceptual expertise, we recorded ERPs while participants performed a categorization task. We found that as participants learned to discriminate computer generated "blob" stimuli, ...
