Phosphorylation-dependent trafficking of GluR2-containing AMPA receptors in the nucleus accumbens plays a critical role in the reinstatement of cocaine seeking.

20 Oct 2008 A growing body of evidence indicates that enhanced AMPA-mediated glutamate transmission in the core of the nucleus accumbens is critically involved in cocaine priming-induced reinstatement of drug seeking, an animal model of relapse. However, the ...

Post-training self administration of sugar facilitates cognitive performance of male C57BL/6J mice in two spatial learning tasks.

16 Oct 2008 Spatial memory can be strengthened by adverse stimuli that activate the stress system, and administration of the stress hormone corticosterone in close-context with the learning task. Less is known about modulation of spatial memory by post-training ...

Dynamic changes in dopamine tone during self-stimulation of the ventral tegmental area in rats.

16 Oct 2008 In a prior study, phasic release of dopamine (DA) in the nucleus accumbens (NAc) was only transiently and rarely detected by means of fast-scan cyclic voltammetry (FCSV) in rats already trained to work for electrical stimulation of the ventral ...

Oscillations following periodic reinforcement.

15 Oct 2008 Three experiments examined behavior in extinction following periodic reinforcement. During the first phase of Experiment 1, four groups of pigeons were exposed to fixed interval (FI 16s or FI 48s) or variable interval (VI 16s or VI 48s) ...

Pre-surgical training ameliorates orbitofrontal-mediated impairments in spatial reversal learning.

13 Oct 2008 We recently reported that orbitofrontal cortical (OFC) lesions impaired reversal learning of an instrumental two-lever spatial discrimination task, a deficit manifested as increased perseveration on the pre-potent response. Here we examine whether ...

NMDA receptor antagonism in the ventral tegmental area impairs acquisition of reward-related learning.

13 Oct 2008 Mechanisms underlying reward-related learning presumably involve neural plasticity integrating signals representing unconditioned and conditioned stimuli in regions mediating reward. The ventral tegmental area (VTA) receives such signals and shows ...

Using a Time Timer to increase appropriate waiting behavior in a child with developmental disabilities.

13 Oct 2008 This study aimed to examine the use of a predictive stimulus (Time Timer) and delayed reinforcement to increase appropriate waiting behavior in a child with developmental disabilities and problem behavior maintained by access to tangible items and ...

Feature-short and feature-long discrimination learning in the pigeon: conditional control of a two-event temporal map.

9 Oct 2008 Eight pigeons were trained to peck an illuminated target key on discrete-trial fixed-interval schedules of reinforcement by food. Four birds were exposed to a feature-short (FS) task where a feature light signaled shortening of the forthcoming ...

D-cycloserine enhances short-delay, but not long-delay, conditioned taste aversion learning in rats.

5 Oct 2008 NMDA receptors have been implicated in conditioned taste aversion (CTA), a form of associative learning with the unique temporal characteristic of associating taste and toxic stimuli across very long delays. d-cycloserine (DCS), an NMDA receptor ...

Super-additive interaction of the reinforcing effects of cocaine and H1-antihistamines in rhesus monkeys.

5 Oct 2008 Histamine H1 receptor antagonists can be sedating and have behavioral effects, including reinforcing and discriminative stimulus effects in non-humans, that predict abuse liability. Previous research has suggested that antihistamines can enhance the ...
