Valuation of uncertain and delayed rewards in primate prefrontal cortex.
27 Mar 2009 
Humans and animals often must choose between rewards that differ in their qualities, magnitudes, immediacy, and likelihood, and must estimate these multiple reward parameters from their experience. However, the neural basis for such complex decision ...

Effects of cues associated with meal interruption on feeding behavior.
26 Mar 2009 Food consumption is controlled by both internal and external factors. Environmental signals associated with food may prepare an animal to forage, consume and digest more effectively. Furthermore, environmental cues that provide information about ...

Parameters of rewards on choice behavior in Siamese fighting fish (Betta splendens).
26 Mar 2009 Five experiments were conducted with Siamese fighting fish (Betta splendens) to investigate how choices in a T-maze were affected by parameters of a social reward (aggression display to another male): presence or absence, amount, delay and distance ...

26 Mar 2009 Psychostimulant addicts often take high doses of drugs, and high doses of psychostimulants such as methamphetamine (METH) are neurotoxic to striatal dopamine (DA) terminals. Yet, the effects of high doses of METH on drug-seeking and drug-taking ...

Agmatine blocks acquisition and re-acquisition of intravenous morphine self-administration in rats.
25 Mar 2009 Our previous studies showed that agmatine inhibits morphine-induced conditioned place preference, locomotor sensitization and drug discrimination in rats. In the present study, we investigated the effects of agmatine on intravenous morphine ...

Comparing preference assessments: selection- versus duration-based preference assessment procedures.
24 Mar 2009 In the current investigation, the results of a selection- and a duration-based preference assessment procedure were compared. A Multiple Stimulus With Replacement (MSW) preference assessment [Windsor, J., Piché, L. M., & Locke, P. A. (1994). ...

Dopamine DRD2 polymorphism alters reversal learning and associated neural activity.
23 Mar 2009 In humans, presence of an A1 allele of the DRD2/ANKK1-TaqIa polymorphism is associated with reduced expression of dopamine (DA) D(2) receptors in the striatum. Recently, it was observed that carriers of the A1 allele (A1+ subjects) showed impaired ...

Goal-directed control and its antipodes.
22 Mar 2009 In instrumental conditioning, there is a rather precise definition of goal-directed control, and therefore an acute boundary between it and the somewhat more amorphous category comprising its opposites. Here, we review this division in terms of the ...

22 Mar 2009 A novel reinforcement-learning-based output adaptive neural network (NN) controller, which is also referred to as the adaptive-critic NN controller, is developed to deliver the desired tracking performance for a class of nonlinear discrete-time ...

22 Mar 2009 The motivational effects of drugs play a key role during the transition from casual use to abuse and dependence. Ethanol reinforcement has been successfully studied through Pavlovian and operant conditioning in adult rats and mice genetically ...
