abstract：:Exposure to 10 min of footshock stress (1 mA; 0.5 s on, with a mean off period of 40 s) reinstated heroin-seeking behavior in heroin-experienced, drug-free rats after many sessions of extinction and up to 6 weeks after last exposure to heroin. In reinstating the behavior, the footshock mimicked the effect of a non-con...
