Effects of oxazepam on anxiety: implications for Fowles' psychophysiological interpretation of Gray's model.

abstract：RATIONALE:Understanding factors contributing to individual differences in vulnerability to opioid addiction is essential for developing more effective preventions and treatments, yet few reliable behavioral predictors of subsequent opioid self-administration have been identified in rodents. Sensitivity to the acute eff...
