Figure 3. Exp. 2: Food: Effect of prazosin or guanfacine on yohimbine-induced reinstatement.

Figure 3

Data are mean±SEM presses on the previously active lever and mean±SEM magazine entries. (A, B) Effect of prazosin or guanfacine on yohimbine-induced reinstatement (n=12 per drug condition, within-subjects design). (C) Effect of guanfacine on yohimbine-induced reinstatement in groups of rats that either decreased (n=7) or not decreased (n=5) yohimbine-induced reinstatement after guanfacine injections. The rats were injected with prazosin, guanfacine or their vehicles 60 min before the test sessions, and then injected with yohimbine or its vehicle 45 min before these sessions. * Different from the appropriate prazosin or the guanfacine vehicle condition, p < 0.05.
