Anatomical and functional refinements of the meso-limbic dopamine system of the rat are
discussed. Present experiments suggest that dopaminergic neurons localized in the …

Studies addressing behavioral functions of dopamine (DA) in the nucleus accumbens septi
(NAS) are reviewed. A role of NAS DA in reward has long been suggested. However, some …

Rationale: Among the various experimental protocols that have been used to measure drug
reward in laboratory animals, conditioned place preference (CPP) has been one of the most …

This review gives an overview of recent findings and developments in research on brain
mechanisms of reward and reinforcement from studies using the place preference …

While it has previously been assumed that mesolimbic dopamine neurons carry a reward
signal, recent data from single-unit, microdialysis and voltammetry studies suggest that …

Compared to the study of negative emotions such as fear, the neurobiology of positive
emotional processes and the associated positive affect (PA) states has only recently …

The mesolimbic dopaminergic (ML-DA) system has been recognized for its central role in
motivated behaviors, various types of reward, and, more recently, in cognitive processes …

Amphetamine microinjection into the nucleus accumbens shell enhanced the ability of a
Pavlovian reward cue to trigger increased instrumental performance for sucrose reward in a …

There is considerable evidence that high novelty seekers are at increased risk for using
drugs of abuse relative to low novelty seekers. This review examines the potential biological …

Previous studies have demonstrated that central administration of vasopressin but not
oxytocin facilitates pair bonding in the monogamous male prairie vole. This study tested …
