7 Apr 2009 
Previous experiments using progressive-delay schedules showed that destruction of the nucleus accumbens core (AcbC) altered rats' choice between food reinforcers differing in size and delay. Application of a quantitative model of inter-temporal ...

Effort-based cost-benefit valuation and the human brain.
6 Apr 2009 In both the wild and the laboratory, animals' preferences for one course of action over another reflect not just reward expectations but also the cost in terms of effort that must be invested in pursuing the course of action. The ventral striatum ...

Associative theories of goal-directed behaviour: a case for animal-human translational models.
5 Apr 2009 
Associative accounts of goal-directed action, developed in the fields of human ideomotor action and that of animal learning, can capture cognitive belief-desire psychology of human decision-making. Whereas outcome-response accounts can account for ...

The nucleus accumbens: a switchboard for goal-directed behaviors.
5 Apr 2009 Reward intake optimization requires a balance between exploiting known sources of rewards and exploring for new sources. The prefrontal cortex (PFC) and associated basal ganglia circuits are likely candidates as neural structures responsible for ...

Adaptive learning via selectionism and Bayesianism, Part II: the sequential case.
3 Apr 2009 Animals increase or decrease their future tendency of emitting an action based on whether performing such action has, in the past, resulted in positive or negative reinforcement. An analysis in the companion paper [Zhang, J. (2009). Adaptive ...

Adaptive learning via selectionism and Bayesianism, Part I: connection between the two.
3 Apr 2009 According to the selection-by-consequence characterization of operant learning, individual animals/species increase or decrease their future probability of action choices based on the consequence (i.e., reward or punishment) of the currently ...

Chronic treatment with monoamine oxidase-B inhibitors decreases cocaine reward in mice.
Apr 2009 RATIONALE AND OBJECTIVE: Whether monoamine oxidase inhibitors (MAOIs) can be used to suppress the reinforcing effect of cocaine remains unknown. This study was undertaken to examine effects of a long-term dosing regimen with selective MAOIs on ...

31 Mar 2009 RATIONALE AND OBJECTIVES: The melanin-concentrating hormone 1 (MCH1) receptors play an important role in home-cage food consumption in rodents, but their role in operant high-fat food-reinforced responding or reinstatement of food seeking in animal ...

31 Mar 2009 Histamine 3 (H(3)) receptors are distributed throughout the brain and regulate histamine as well as the activity of other neurotransmitters including acetylcholine (ACh). Impaired ACh neurotransmission is associated with deficits of ...

31 Mar 2009 In behavioral experiments, cats placed in a situation of choosing between a high-value time-delayed and a low-value rapid food reinforcement elected to wait for the preferred reward (they demonstrated "self-control") or to obtain the worse reward ...
