Environment-dependent effects of ethanol on DOPAC and HVA in various brain regions of ethanol-tolerant rats.

abstract：RATIONALE:Mice are useful tools for dissecting genetic and environmental factors in relation to the study of attention and impulsivity. The five-choice serial reaction time task (5CSRTT) paradigm has been well established in rats, but its transferability to mice is less well documented. OBJECTIVES:This study aims to s...
