Relationship between rate of infusion and reinforcing strength of oxycodone in humans.

29 Jun 2009 The rate of drug delivery to the central nervous system is believed to be an important predictor of the reinforcing strength of a drug. However, only a few studies have directly examined the relationship between drug-taking behavior and rate of drug ...

Behavioral momentum of cocaine self-administration: effects of frequency of reinforcement on resistance to extinction.

29 Jun 2009 Persistent drug seeking is a defining property of substance abuse and is generally thought to depend, in part, on exposure to drug-associated contexts. Behavioral momentum theory provides a set of methods and a theoretical framework for ...

Single dose of a dopamine agonist impairs reinforcement learning in humans: evidence from event-related potentials and computational modeling of striatal-cortical function.

29 Jun 2009 Animal findings have highlighted the modulatory role of phasic dopamine (DA) signaling in incentive learning, particularly in the acquisition of reward-related behavior. In humans, these processes remain largely unknown. In a recent study, we ...

Dorsal striatal-midbrain connectivity in humans predicts how reinforcements are used to guide decisions.

29 Jun 2009 It has been suggested that the target areas of dopaminergic midbrain neurons, the dorsal (DS) and ventral striatum (VS), are differently involved in reinforcement learning especially as actor and critic. Whereas the critic learns to predict rewards, ...

Computational perspectives on forebrain microcircuits implicated in reinforcement learning, action selection, and cognitive control.

28 Jun 2009 Abundant new information about signaling pathways in forebrain microcircuits presents many challenges, and opportunities for discovery, to computational neuroscientists who strive to bridge from microcircuits to flexible cognition and action. ...

Lateralized processes constrain auditory reinforcement in human newborns.

25 Jun 2009 We investigated operant sucking response learning in human newborns. Auditory reinforcers always occurred monaurally to see whether their potency differed between ears. Experiment 1 - we controlled the reinforcers, either intrauterine heartbeat ...

The influence of context valence in the neural coding of monetary outcomes.

24 Jun 2009 The emotional significance of objects and events depends on the context in which they occur. Using functional magnetic resonance imaging, we examined the modulation of neural responses to monetary outcomes while subjects performed a decision-making ...

Lack of effect of habenula lesion on heroin self-administration in rats.

15 Jun 2009 We examined the effects of bilateral electric lesion of the habenula (Hb) on the acquisition and maintenance of heroin self-administration. The rats were trained to self-administer heroin (0.05 mg/kg/infusion) under FR1 schedule in daily 4h ...
