Nuclei accumbens phase synchrony predicts decision-making reversals following negative feedback.

8 Jun 2009 The nucleus accumbens plays a key role in reinforcement-guided behaviors. Here, we report that electrophysiological oscillatory phase synchrony between the two nuclei accumbens may play a crucial role in using negative feedback to guide decision ... Read more...

Adaptive coding of action values in the human rostral cingulate zone.

8 Jun 2009 Correctly selecting appropriate actions in an uncertain environment requires gathering experience about the available actions by sampling them over several trials. Recent findings suggest that the human rostral cingulate zone (RCZ) is important for ... Read more...

Dopamine release in dissociable striatal subregions predicts the different effects of oral methylphenidate on reversal learning and spatial working memory.

13 Apr 2009 Previous data suggest that methylphenidate can have variable effects on different cognitive tasks both within and between individuals. This is thought to be underpinned by inverted U-shaped relationships between cognitive performance and ... Read more...

Technical information about 'Reversal Learning'

Definition: Any situation where an animal or human is trained to respond differentially to two stimuli (e.g., approach and avoidance) under reward and punishment conditions and subsequently trained under reversed reward values (i.e., the approach which was previously rewarded is punished and vice versa).
