Increased expression of the NR2A NMDA receptor subunit in the prefrontal cortex of rats reared in isolation.

29 Sep 2009 A hypofunction of the N-methyl-D-aspartate (NMDA) receptor has been implicated in the pathophysiology of schizophrenia. Compelling evidence of altered NMDA receptor subunit expression in the schizophrenic brain has not, however, so far emerged. Rats ... Read more...

Dopamine is necessary for cue-dependent fear conditioning.

7 Sep 2009 Dopamine (DA) is implicated in many behaviors, including motor function, cognition, and reward processing; however, the role of DA in fear processing remains equivocal. To examine the role of DA in fear-related learning, dopamine-deficient (DD) mice ... Read more...

Evidence for a putative biomarker for substance dependence.

30 Aug 2009 Electrodermal response modulation (ERM) reflects the reduction in skin conductance response to an aversive stimulus that is temporally predictable relative to when it is unpredictable. Poor ERM is associated with substance dependence (SD). It was ... Read more...
