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, ...

27 Jun 2009 Gamma-hydroxybutyrate (GHB) is used therapeutically and recreationally. The mechanism by which GHB produces its therapeutic and recreational effects is not entirely clear, although GABA(B) receptors seem to play an important role. This role could be ...

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 ...

22 Jun 2009 The role of adult brain neurogenesis (generating new neurons) in learning and memory appears to be quite firmly established in spite of some criticism and lack of understanding of what the new neurons serve the brain for. Also, the few experiments ...

Side-specific reward memories in honeybees.
22 Jun 2009 We report a hitherto unknown form of side-specific learning in honeybees. We trained bees individually by coupling gustatory and mechanical stimulation of each antenna with either increasing or decreasing volumes of sucrose solution offered to the ...

15 Jun 2009 Pathological gambling (PG) is characterized by persistent, maladaptive gambling behavior, which disrupts personal and professional life. Animal models of gambling behavior could make a significant contribution to improving our understanding of the ...

14 Jun 2009 Natural polymorphisms at the foraging (for) gene influence several behaviors. However, it is seldom clear how different for alleles could be selected. In one case, Drosophila with the rover allele (for(r)) have higher locomotor activity in the ...

Mouse model of OPRM1 (A118G) polymorphism has sex-specific effects on drug-mediated behavior.
13 Jun 2009 A single nucleotide polymorphism (SNP) in the human mu-opioid receptor gene (OPRM1 A118G) has been widely studied for its association in a variety of drug addiction and pain sensitivity phenotypes; however, the extent of these adaptations and the ...

Gender differences in delay-discounting under mild food restriction.
6 Jun 2009 Impulsivity, a core symptom of attention-deficit hyperactivity disorder (ADHD), is tested in animal models by delay-discounting tasks. So far, mainly male subjects have been used in this paradigm at severe levels of food restriction. Here we studied ...

4 Jun 2009 In most models of perceptual learning, the amount of improvement of performance does not depend on the regime of stimulus presentations, but only on the sheer number of trials. Here, we kept the number of stimulus presentations constant while ...
