Reward-seeking and discrimination deficits displayed by hypodopaminergic mice are prevented in mice lacking dopamine D4 receptors.

30 Oct 2009 The dopamine D4 receptor (D4R) is predominantly expressed in the prefrontal cortex, a brain area that integrates motor, rewarding, and cognitive information. Because participation of D4Rs in executive learning is largely unknown, we challenged D4R ... Read more...

Ventral striatal neurons encode the value of the chosen action in rats deciding between differently delayed or sized rewards.

19 Oct 2009 The ventral striatum (VS) is thought to serve as a gateway whereby associative information from the amygdala and prefrontal regions can influence motor output to guide behavior. If VS mediates this "limbic-motor" interface, then one might expect ... Read more...

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...
