A neurocomputational model for cocaine addiction.

29 Sep 2009 Based on the dopamine hypotheses of cocaine addiction and the assumption of decrement of brain reward system sensitivity after long-term drug exposure, we propose a computational model for cocaine addiction. Utilizing average reward temporal ... Read more...

Functional significance of nonspatial information in monkey lateral intraparietal area.

22 Jun 2009 Although the parietal cortex is traditionally associated with spatial perception and motor planning, recent evidence shows that neurons in the lateral intraparietal area (LIP) carry both spatial and nonspatial signals. The functional significance of ... Read more...

Impairment of cognitive abilities and decision making after chronic use of alcohol: the impact of multiple detoxifications.

30 May 2009 AIMS: In the present study, the effect of previous detoxifications on prefrontal function and decision making was examined in alcohol-dependent patients. Further, we examined whether the length of abstinence affects cognitive function. METHODS: ... Read more...
