Altered corticostriatal functional connectivity in obsessive-compulsive disorder.

30 Oct 2009 CONTEXT: Neurobiological models of obsessive-compulsive disorder (OCD) emphasize disturbances in the function and connectivity of brain corticostriatal networks, or "loops." Although neuroimaging studies of patients have supported this network model ... Read more...

Altered effect of dopamine transporter 3'UTR VNTR genotype on prefrontal and striatal function in schizophrenia.

30 Oct 2009 CONTEXT: The dopamine transporter plays a key role in the regulation of central dopaminergic transmission, which modulates cognitive processing. Disrupted dopamine function and impaired executive processing are robust features of schizophrenia. ... 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...
