The computation of social behavior.
27 May 2009 
Neuroscientists are beginning to advance explanations of social behavior in terms of underlying brain mechanisms. Two distinct networks of brain regions have come to the fore. The first involves brain regions that are concerned with learning about ...

19 May 2009 This study investigated the extent to which hydromorphone (HYD) choice and behavioral economic demand were influenced by HYD unit price (UP), alternative money reinforcement magnitude and post-session HYD supply. Heroin-dependent research volunteers ...

18 May 2009 BACKGROUND: Food reinforcement, ie, motivation to obtain food, is associated with energy intake and obesity. Finding ways to decrease the reinforcing value of unhealthy foods may help with adherence to diets and maintenance of weight loss. Our ...

Prolonged exposure to denicotinized cigarettes with or without transdermal nicotine.
13 May 2009 Sensorimotor smoking stimuli are important determinants of cigarette use. The present study aimed to determine whether denicotinized cigarettes lose their reinforcing and/or subjective effects over a 9-day outpatient period when they are smoked with ...

Genome-wide analysis of chromatin regulation by cocaine reveals a role for sirtuins.
12 May 2009 Changes in gene expression contribute to the long-lasting regulation of the brain's reward circuitry seen in drug addiction; however, the specific genes regulated and the transcriptional mechanisms underlying such regulation remain poorly ...

Rapid matching in Drosophila place learning.
11 May 2009 The level of conditioned behavior in animals is proportional to the intensity, amount, frequency, or probability of reinforcement. Interestingly, this matching can be dynamic, with performance levels following, for example, a switch in the ...

Neural correlates of risk prediction error during reinforcement learning in humans.
11 May 2009 Behavioral studies have shown for decades that humans are sensitive to risk when making decisions. More recently, brain activities have been shown to be correlated with risky choices. But an important gap needs to be filled: How does the human brain ...

Dopamine, reinforcement learning, and addiction.
9 May 2009 Dopamine is intimately linked with the modes of action of drugs of addiction. However, although its role in the initiation of drug abuse seems relatively uncomplicated, its possible involvement in the development of compulsive drug taking, and ...

Dynamics of neuronal circuits in addiction: reward, antireward, and emotional memory.
9 May 2009 Drug addiction is conceptualized as chronic, relapsing compulsive use of drugs with significant dysregulation of brain hedonic systems. Compulsive drug use is accompanied by decreased function of brain substrates for drug positive reinforcement and ...

Systems biology and addiction.
9 May 2009 The onset of addiction is marked with drug induced positive experiences that keep being repeated. During that time, adaptation occurs and addiction is stabilized. Interruption of those processes induces polysymptomatic withdrawal syndromes. ...
