Drug-seeking behavior after lidocaine inactivation of the caudal basolateral amygdala (n = 5). Responses on the active lever are shown on the top, and responses on the inactive lever are shown on the bottomfor each phase of the experiment: discrimination baseline, extinction, drug cue-induced reinstatement, and drug prime plus drug cue-induced reinstatement conditions. Values are the mean ± SEM. S⁺ refers to the drug-associated cues, and S⁻ refers to the saline-associated cues. *Significantly different (p ≤ 0.05) from the appropriate control value. See Results for statistical details.
