Long-lasting yohimbine effects, a Preference for the large reward in the ascending delays discounting task, b Preference for the large reward in the descending delays task on the day preceding yohimbine administration, c Effect of acute administration of yohimbine on reward preference in the descending delays task, d–f Yohimbine administration had long-lasting effects on choice behavior in a subset of rats when tested in subsequent drug-free sessions, g Delay discounting behavior after extensive retraining in the descending delays task. * denotes significance vs. pre-yohimbine preference within a specific block (p < 0.01). Symbols indicate mean preference ± SEM
