Levels of gamma-aminobutyric acid (GABA) and its synthesizing enzyme in cerebral cortex are regulated by sensory experience. Previously we found that associative pairing of vibrissae stimulation and tail shock results in upregulation of GABAergic ...

A neural circuit mechanism integrating motivational state with memory expression in Drosophila.
14 Oct 2009 Behavioral expression of food-associated memory in fruit flies is constrained by satiety and promoted by hunger, suggesting an influence of motivational state. Here, we identify a neural mechanism that integrates the internal state of hunger and ...

Writing memories with light-addressable reinforcement circuitry.
14 Oct 2009 Dopaminergic neurons are thought to drive learning by signaling changes in the expectations of salient events, such as rewards or punishments. Olfactory conditioning in Drosophila requires direct dopamine action on intrinsic mushroom body neurons, ...

Analgesia accompanying food consumption requires ingestion of hedonic foods.
12 Oct 2009 Animals eat rather than react to moderate pain. Here, we examined the behavioral, hedonic, and neural requirements for ingestion analgesia in ad libitum fed rats. Noxious heat-evoked withdrawals were similarly suppressed during self-initiated ...

Factors governing single-trial contextual fear conditioning in the weanling rat.
29 Sep 2009 Although contextual fear conditioning emerges later in development than explicit-cue fear conditioning, little is known about the stimulus parameters and biological substrates required at early ages. The authors adapted methods for investigating ...

Appetitively motivated instrumental learning in SynGAP heterozygous knockout mice.
29 Sep 2009 The synaptic Ras/Rap-GTPase-activating protein (SynGAP) regulates specific intracellular events following N-methyl-d-aspartate receptor (NMDAR) activation. Here, the impact of SynGAP heterozygous knockout (SG+/-) on NMDAR-dependent functions was ...

29 Sep 2009 The orexigenic neuropeptide ghrelin is an endogeneous ligand for the growth hormone secretagogue receptor (GHS-R). This orexigen is expressed in both the periphery and in the central system, including portions of mesolimbic dopaminergic circuitry ...

29 Sep 2009 Long-term cognitive impairments are a feared consequence of therapeutic cranial irradiation in children as well as adults. Studies in animal models suggest that these deficits may be associated with a decrease in hippocampal granule cell ...

Dynamic computation of incentive salience: "wanting" what was never "liked".
28 Sep 2009 Pavlovian cues for rewards become endowed with incentive salience, guiding "wanting" to their learned reward. Usually, cues are "wanted" only if their rewards have ever been "liked," but here we show that mesocorticolimbic systems can recompute ...

Changes in rapid eye movement sleep associated with placebo-induced expectations and analgesia.
21 Sep 2009 The experience of a sensory event is extensively shaped by past experience and expectations. Placebo analgesia, one of the most studied models of expectation-mediated effects, can be induced by suggestion of analgesia and conditioning. The present ...
