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 ... Read more...

Doomed to repeat the successes of the past: history is best forgotten for repeated choices with nonstationary payoffs.

29 Sep 2009 Many everyday tasks involve repeated choices in which past outcomes are used to estimate payoffs but in which present payoffs may differ from past ones. Two experiments with 10 decision problems employing the decisions-from-feedback paradigm ... Read more...

c-Fos expression associated with reinstatement of cocaine-seeking behavior by response-contingent conditioned cues.

29 Sep 2009 The capability of cocaine cues to generate craving in cocaine-dependent humans, even after extended abstinence, is modeled in rats using cue reinstatement of extinguished cocaine-seeking behavior. We investigated neural activity associated with ... Read more...
