Age-related scopolamine effects on social and individual behaviour in rats.

abstract：:The current study examined whether stimuli predictive of heroin availability were capable of inducing a relapse of drug-seeking behavior in an operant runway task. Olfactory stimuli (orange and almond food extract) served as discriminative cues about the availability (S+) or unavailability (S-) of heroin reinforcement...
